DETAILED DESCRIPTION OF THE EMBODIMENTS

[0054] Welder qualification coupons are used to qualify welders where RT along with the destructive bend test are the primary methods before work can be done on a project such as, but not limited to, energy and other refineries facilities. These coupons are what the welder is to use for quality testing, such as two pipe segments with a specific bevel that is defined in the construction codes such as the American Society of Mechanical Engineers (ASME) or other code standards. It can be appreciated that the 280 union halls and trade schools in North America use coupons and test methods. Over the past decades, radiographic film processing versus digital has maintained 85% film processing. Remote third-party inspection companies often perform the evaluation either onsite at the facility (which required increased costs for permitting and potential source management) or the coupons are sent to their facility often in batches that can present delays in pass/fail results to the welders.

[0055] Another concern impacting performance, productivity, and prices when new welders enter the industry, are that the evaluation metrics are to pass radiography which is often film. As more and more jobs are using Phased Array Ultrasonic Testing (PAUT) in lieu of RT, for example in the nuclear industry, the welder often fails performance tests with ultrasonics due to the different discontinuities it detects. RT presents 2D discontinuities, and the bend-test does not focus on the complete circumference of the weld. PAUT detects 3D indications/reflectors as sound waves are angled by a time sequencing pulse. This easily detects the lack of sidewall fusion and cracks and can inspect the entire weld in a single pass without chemicals, radiation, or processing time. Additionally, domestic welders often have an adaptive period when they are placed on jobs where PAUT in lieu of Radiography is performed. This can have a significant impact on-time schedules, initially reject rates, and overall costs of the projects. Embracing ultrasonic inspections early in the training process can amend the overall skill mismatch while increasing productivity through faster feedback and developing inspection methods widely used in the nuclear industry.

[0056] Welder certifications with RT are slow, as radiographs are time-consuming with the potential day turnaround at best from the third-party non-destructive testing companies. Another concern is that the welder is trained to pass radiography, but not necessarily the discontinuities picked up by advanced ultrasonics like a phased array. RT is excellent for porosity as the density difference is significant enough but misses cracks and lack of sidewall fusion.

[0057] Another disadvantage of using film radiography is that the film must be stored in a controlled environment and often the welder just receives a report. As digitalization becomes increasingly important migrating away from film radiography will occur. As such, PAUT is a viable option for traceability of welder evaluation/certification at production that can be linked directly to the NDE method, inspector, and report for end-to-end linkage at every weld.

[0058] The continued reliance on radiography to certify welders has created a dilemma for the welding industry. The resulting problem, however, is that PAUT and RT have different sensitivity to the various defects that can be generated where RT does not distinguish depth and PAUT can meet workmanship acceptance criteria. RT can be used to detect density differences as the radiation passes through the specimen and is very useful for finding imperfections like porosity, slag, and undercuts that are mass-based distinctions. It uses diffracted, high-frequency sound beams that can not only detect mass-based defects but can also detect non-mass defects like cracks and lack of sidewall fusion. As a result, welders are trained to meet the detection capabilities of the radiographic method versus one that is transitioning into widespread use for production quality control.

[0059] A couple of industry trends have been recognized that impact the fabrication and maintenance through the welding trade. One of these trends is that the welding industry is losing a vital workforce, as stated in The American Welding Society that estimates there will be a shortage of more than 400,000 welders by 2024. This lack of position fulfillment is even more exacerbated in that these positions are not backfilled with the younger generation.

[0060] Another trend is that welders are trained to pass radiography tests and fail when put on a job using ultrasonics in lieu of radiography. Technology is not bridging the gap between skill and need in the digital transformation.

[0061] Current condition systems may include bend test, which is a sampling of areas that may/may not represent total skill/performance, or third-party RT which may be costly, including time delay and not representative of the project evaluation process

[0062] Therefore, what is needed is an alternative quality evaluation/inspection method closer to the welder craft during training, performance demonstrations, and evaluation.

[0063] While the above-described devices fulfill their respective, particular objectives and requirements, the aforementioned devices or systems do not describe an ultrasound-based welder qualification system that allows automated rapid inspection and delivery of welding during training in accordance with certification parameters. The present technology additionally overcomes one or more of the disadvantages associated with these known systems by utilizing an adjustable ultrasonic probe assembly in an automated process to rapidly provide weld quality data to a welder, instructor and/or other third party.

[0064] A need exists for a new and novel ultrasound-based welder qualification system that can be used for automated rapid inspection and delivery of welding during training in accordance with certification parameters. In this regard, the present technology substantially fulfills this need. In this respect, the ultrasound-based welder qualification system according to the present technology substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of automated rapid inspection and delivery of welding during training in accordance with certification parameters.

[0065] In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular embodiments, procedures, techniques, etc. in order to provide a thorough understanding of the present technology. However, it will be apparent to one skilled in the art that the present technology may be practiced in other embodiments that depart from these specific details.

[0066] In the following detailed description of the invention, numerous details, examples, and embodiments of the invention are described. However, it will be clear and apparent to one skilled in the art that the invention is not limited to the embodiments set forth and that the invention can be adapted for any of several applications.

[0067] In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular embodiments, procedures, techniques, etc. in order to provide a thorough understanding of the present invention. However, it will be apparent to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details.

[0068] Generally, the present disclosure pertains to apparatus, systems and/or methods for automated rapid inspection and delivery of welder performance results during training in accordance with certification parameters.

[0069] Some embodiments include an ultrasound-based welder qualification system. In some embodiments, the ultrasound-based welder qualification system utilizes a close-loop ultrasonic testing inspection system in lieu of radiographic testing and mechanical bend tests. In some embodiments, the ultrasound-based welder qualification system includes an inspection coupon manipulation system with an ultrasonic probe placement system for welder qualification coupons with a development path for machine learning assisted analysis according to relevant codes/standards. In some embodiments, the ultrasound-based welder qualification system uses acquired data to refine the machine learning algorithms for the automated assisted analysis in accordance with accepted industry standards. In some embodiments, the cabinet entails an enclosed mechanical encoded rotation system for coupon placement, a probe positioning device with water/coolant effluent removal. In some embodiments, the ultrasonic probe is part of an advanced ultrasonic pulsing system.

[0070] In some embodiments, the ultrasound-based welder qualification system also includes a computing device with a software implementation of the process (“system software”) for specific coupon selection and acquisition of data. In some embodiments, the system software includes a recipe-driven coupon selection interface. In some embodiments, the ultrasound-based welder qualification system connects to a Computer Aided Device (CAD) 3-dimensional modeling system. Thus, following acquisition, the encoded data output populates into the CAD 3-dimensional modeling system. Subsequent validation efforts are performed via machine learning. In some embodiments, the ultrasound-based welder qualification system uses Python-based machine learning algorithms for automated assisted analysis in accordance to accepted industry standards. In some embodiments, the machine learning provides auto-detection plot for discontinuities. It can be appreciated that use of other machine learning algorithms in place of Python-learning may be utilized with some embodiments of the present technology.

[0071] In some embodiments, the ultrasound-based welder qualification system delivers code/standard evaluation onsite for a welder during training, performance demonstrations, and evaluation. In some embodiments, the onsite ultrasound-based welder qualification system provides external cloud connectivity for enhanced development of the algorithms accuracy. The additional feedback can be provided at the Union Hall level for student performance metrics to enhance training program.

[0072] As stated above, current solutions for welder qualifications are outsourced 3rd party radiographic film and/or destructive bend tests. Embodiments of the invention described in this specification solve such problems by an ultrasound-based welder qualification system that is a self-contained mechanical ultrasonic solution not requiring permitting or third party execution, but provides onsite feedback closer to the welder to elevate the craft.

[0073] Embodiments of the ultrasound-based welder qualification system described in this specification differ from and improve upon currently existing options. In particular, some embodiments differ by providing faster feedback of inspection, digital results, and data tracking for institution executing training. The controlled data acquisition strategy provides purer ground-truth data files for training/programming development of AI/ML. In addition, the ultrasound-based welder qualification system of some embodiments utilizes a close-loop ultrasonic testing inspection system in lieu of radiographic testing and mechanical bend tests. Also, radiographic testing and bend tests work in the legacy fashion, destructive and two-dimensional, but the ultrasound-based welder qualification system described in this specification elevates the speed and provides 3D results.

[0074] The ultrasound-based welder qualification system of the present disclosure may be comprised of the following elements. This list of possible constituent elements is intended to be exemplary only and it is not intended that this list be used to limit the ultrasound-based welder qualification system of the present application to just these elements. Persons having ordinary skill in the art relevant to the present disclosure may understand there to be equivalent elements that may be substituted within the present disclosure without changing the essential function or operation of the ultrasound-based welder qualification system.

[0081] 7. Once complete the ultrasonic probe mechanism returns to the home position

[0082] 8. Cabinet door releases

[0083] 9. Acquired data imports into evaluation software

[0084] 10. After a defined acquisition for variation of pipe weld coupons data will be aggregated to train ML

[0085] 11. After ML is trained, auto reporting of welder performance will grade the results and CAD drawing display for visualized plotted results

[0086] The various elements of the ultrasound-based welder qualification system of the present disclosure may be related in the following exemplary fashion. It is not intended to limit the scope or nature of the relationships between the various elements and the following examples are presented as illustrative examples only. The enclosure houses the rotation system for the coupons, a separate program engages the positional system. The software on the computer engages the acquisition software, the probe mechanism and the encoded rotation system. The retraction of the probe mechanism and release of cabinet safety feature.

[0087] The ultrasound-based welder qualification system of the present disclosure generally works as a standalone unit that collectively receives the welder qualification coupon, rotates, positions probes, acquires the data and releases. Uploading the data for assisted analysis annotation for rapid compliance response to a welder with visual CAD-like representation for increased insight into craft/skill. In some embodiments, a computing device drives the overall process, sub routines are the locking/unlocking safety mechanism, subroutine synced with the rotation system and import into the computer. In some embodiments, the AI/ML modules are implemented as a subsequent process, taking the exported data as data to train the machine learning aspect.

[0088] To make the ultrasound-based welder qualification system of the present disclosure, one would provide a closed cabinet that houses a caster rotation system entailing 1/2 drive wheels and one encoder wheel for data tracing. The auto probe placement system will be engaged from the remote laptop computing device that engages once a coupon is placed and the cabinet is securely closed. The exported data will be used to train machine learning for assisted analysis. The implementation of the software system will also allow remote access for performance analytics. The mechanical components include at least the cabinet, casters (drive and encoder), couplant/water delivery system, probes contoured to appropriate diameters (2″-10″). Digital aspects include a computer, pulser module and offsite communications. Probe assemblies typically preferred as being interchangeable to accommodate proper coupling on various diameters. The auto probe placement system can be engaged from a computing onboard system that engages once a coupon is placed and the cabinet is securely closed.

[0089] To use the ultrasound-based welder qualification system of the present disclosure, a welder would provide a coupon to the cabinet and begin the evaluation. This is preferred over the current welder qualification processes which require 2D radiography performed by a certified 3rd party and often invoke a time delay before feedback offered to welder, while the other validation process (bend test) is destructive in nature.

[0090] Additionally, the ultrasound-based welder qualification system may be adapted for use and utilized in field industrial inspection systems. Also, the ultrasound-based welder qualification system can provide performance data analytics for global training metrics and increased design capabilities.

The horizontal member motor 47 can be supported by either one of the vertical blocks 42, or can be associated with a horizontal motor block (not shown) that travels along one of the vertical drive members 38.

[0114] Two or more horizontal blocks 48a, 48b can operably coupled to the horizontal drive member 46 to provide horizontal movement of the horizontal blocks 48a, 48b upon rotation of the horizontal drive member 46 by the horizontal member motor 47. The horizontal blocks 48a, 48b can be spaced apart on the horizontal drive member 46 so that a first horizontal block 48a is associated with the first coupon section 30a, and a second horizontal block 48b is associated with the second coupon section 30b so that the weld 32 is positioned therebetween. Each of the horizontal blocks 48a, 48b can be independently located or positionable on the horizontal drive member 46. In the exemplary, each of the horizontal blocks 48a, 48b can include a threaded bore that is engageable with a threaded section of the horizontal drive member 46.

[0115] Supported by or suspending from each of the horizontal blocks 48a, 48b is at least one ultrasonic probe 58a, 58b for contact with the first and second coupon sections 30a, 30b, respectively.

[0116] As best illustrated in FIG. 5, a linear slide rail 50 can be attachable to each of the horizontal blocks 48a, 48b for horizontal movement with the horizontal blocks 48a, 48b upon rotation of the horizontal drive member 46. One or more carriages 52a, 52b are each slidable supported on the linear slide rail 50 independent of each other. A first carriage 52a is associated with the first coupon section 30a, and a second carriage 52b is associated with the second coupon section 30b, with the weld 32 positionable therebetween. A locking mechanism can be associated with each of the carriages 52a, 52b to lock the carriages in position along the linear slide rail 50.

[0117] A support member 54a, 54b extends from each of the carriages 52a, 52b, and can be adjustable in length. Each of the probes 58a, 58b can include a probe wedge or probe mount 56a, 56b that is pivotably connected to an end of the support member 54a, 54b, respectively. The pivoting action can be accomplished by a pivot pin 55 passing through the support member 54a, 54b and the probe mount 56a, 56b, thereby providing pivoting or rotation of the probes 58a, 58b in relation to a longitudinal axis of the coupon 30. Alternatively, the pivoting action can be accomplished by a ball and socket connection between the support member 54a, 54b and the probe mount 56a, 56b, thereby providing pivoting or rotation of the probes 58a, 58b in relation to the longitudinal axis and a lateral axis of the coupon 30. This allows for each probe 58a, 58b to be angularly oriented for contact with their corresponding coupon section 30a, 30b. Each of the probes 58a, 58b can be in combination with the computer system 207 by way of cabling/wiring 62.

[0118] A liquid supply tube 60 can be associated with each of the carriages 52a, 52b, each of the support members 54a, 54b or each of the probes 58a, 58b. The liquid supply tube 60 is in communication with the liquid pump 22 so that a liquid such as, but not limited to, water or coolant can be supplied by the liquid pump 22 to an outer surface of the first and second coupon sections 30a, 30b and/or the weld 32 and/or an area adjacent the probes 58a, 58b.

[0119] Horizontal position sensors 49 can be associated with the horizontal drive member 46, the horizontal member motor 47 and/or the horizontal blocks 48a, 48b. The horizontal position sensors are configured or configurable to determine a position of the horizontal blocks 48a, 48b along the horizontal drive member 46. In the exemplary, the horizontal position sensors 49 can be contact switches located a specific locations along the horizontal drive member 46 and/or on any one of or both of the horizontal blocks 48a, 48b. Still further or in the alternative, horizontal position sensors can be associated with the carriages 52a, 52b and/or the support members 54a, 54b. It can be appreciated that the horizontal position sensors 49 can be, but not limited to, distance sensors, laser sensors, travel sensors, and the like.

[0120] In another aspect, one or more horizontal guide members (not shown) can be positioned adjacent to each of the horizontal drive member 46 to guide movement of the horizontal blocks 48a, 48b. In some embodiments, the horizontal guide members can be a horizontal oriented linear slide rail positioned on either side of the horizontal drive member 46. Each linear slide rail can include a corresponding sliding carriage with a connector spanning thereacross and attachable to any one or any combination of the horizontal blocks 48a, 48b. In some embodiments, the horizontal guide members can be horizontal oriented rods that slidably contact a side of any one or any combination of the horizontal blocks 48a, 48b, or any one or any combination of the horizontal blocks 48a, 48b can define bores therethrough configured to slidably receive the horizontal guide rods.

[0121] The top section 70 of the cabinet 14 can have an interior chamber defined by wall panels and configured to contain the computer system 270, and can include a power button 72, a nearfield operator ID device 74, and the display/touchscreen 297.

[0122] The computer system 270 can be in operative communication with the liquid pump 22, the roller motor 28, the vertical member motors 40, the horizontal member motor 47, the vertical position sensors 43, the horizontal position sensors 49, the probes 58a, 58b, and any and all electrical components associated with the system 10. Additionally sensors that can be utilized with the present technology and/or in communication with the computer system 270 can be, but not limited to, distance sensors, contact sensors, temperature sensors, rotation sensors, speed sensors, flow sensors, level sensors, and the like.

[0123] Referring to FIG. 6, a process of the present technology is described which provides operation of the present technology. For exemplary purposes, a software application can be initiated by the user for the automated operation of the system 12. The process can be configured or configurable to initiate subroutines and/or subprocesses to assist in the overall process of the present technology.

[0124] An initial step can be for the user to start the process 80 and power on (step 82) the system. After which, an initialization process is conducted (step 84). The process then proceeds to step 86 wherein a localized system or parameters are loaded.

[0125] Upon which, step 88 initiates a home positioning operation, which controls the auto-positioning of the gantry (step 90) by controlling the y-axis stepper motor and/or the x-axis stepper motor to their retracted positions. The position sensors can be utilized to provide control data for step 90.

[0126] After the gantry is retracted to its home position, step 92 then confirms Wifi and portal connectivity. Welder's information can be provided to the process (step 94) by any suitable means, for example but not limited to, manual entry, remote acquisition and the like. In some embodiments, the welder's information can be provided by way of a V-card that can then be scanned or inputted in to the process. In the exemplary, the V-card can include readable information associated with details of that particular welder, which can be provided by, but not limited to, a barcode or other optical readable code, a Near Field Communication (NFC) system, a Radio-frequency identification (RFID), a magnetic strip or any other known information transmission system. After which, step 96 confirms the welder's information, and this information is then determined if it is registered in step 98. The registration of the welder's information can be accomplished by comparison or cross-referencing with a database. If welder's information is not registered in step 98, then the process proceeds to step 100 that allows the welder details to be entered. The confirmation data from step 96 and the welder's details from step 100 can then be provided as stored data (step 110). The process is capable of created a new welder entry if the welder's information was found in step 98 to not be registered, thereby determining that the welder is a new entry and thus creating a new welder profile including the welder's information.

[0127] The stored data can be provided to the internet and/or network 114, which can be accessed by field resourcing 112, by the present technology system 12 and/or by a remote computer 118. In the exemplary, the field resourcing in step 112 can be utilized with or for, but limited to, union hall performance training, employment companies, welder certification, engineering procurement, etc.

[0128] Still further, third party hosted services for level II's and III's welder certifications can access (step 122) the stored data via the internet and/or network (step 114). This can provide rapid welder certification information to any authorized person. After which, step 124 can be initiated that provides evaluation and annotate from the third party hosted services to provide and/or receive information to the store data.

[0129] Even further, the stored data in step 110 can be provided to and/or receive data from machine learning programming (step 126), which can provide validation (step 128) and verification (step 130) of the information or any results from scans performed on the coupon. After which, the process can proceed to terminate (step 134).

[0130] An additional process can be continued from step 98 if the confirmation data is registered. If the result is “yes” then the process can proceed to step 136 where a scan routine is initiated. Upon which, a coupon is selected (step 138) and then step 140 proceeds to determine if a calibration has been done. If “no” then the process proceeds to step 142 which initiates one or more sequence calibrations, and then the process returns to step 138. It can be appreciated that this provides a process loop until a calibration has been done. A calibration coupon with a predetermined size or diameter and a predetermined weld can be utilized in the system for calibrating the system for operation.

[0131] When a calibration has been determined to be done in step 140, the process then proceeds to step 144 that initiates a routine. After which, a coupon can be placed on the roller assembly or tray (step 146), where confirmation of placement on the roller tray is confirmed (step 148). This can be accomplished by sensors capable of determining a coupon is positioned on the roller assembly. For example, a weight or contact sensor associated with one or more of the rollers, an image of the interior of the coupon receiving section, a laser sensor, and the like.

[0132] After step 148, an auto-positioning process is initiated on the gantry (step 150), wherein the x-axis linear slide rails or horizontal drive member and block carriage, and/or the y-axis ball screw or vertical drive members can be moved. The position of which can be determined by their respective position sensors. This can be accomplished by operating any one of or any combination of the vertical member motors and the horizontal member motor until the ultrasonic probes are in a predetermined or calculated position. Particularly, until the ultrasonic probes are in contact with their respective first and second coupon sections.

[0133] After the auto-positioning of the gantry is completed, the process can proceed to turning “On” a water/couplant sequence (step 152), and then an ultrasonic pulser/receiver procedure can be loaded (step 154). It can be appreciated that a couplant is a material (usually liquid) that facilitates the transmission of ultrasonic energy from a probe/transducer onto a test specimen. Couplant is sometimes necessary because the acoustic impedance mismatch between air and solids (i.e. such as the test specimen) is large.

[0134] Upon completion of step 154, the process can initiate a scan sequence (step 156), which can include the operation of the roller motor to rotate the coupon so that the entire length or circumference of the weld is imaged by the ultrasonic probes. After which, the water sequence can be turned “Off” (step 158) and the gantry can be automatically positioned to a Home position (step 160). The Home position can allow easy access into the interior of the coupon receiving section for removal of the coupon from the roller assembly. The ultrasonic probes provide data to the process for analysis and possible conversion into image data.

[0135] In step 162, the process can then determine if any data from the scan sequence is missing, has been omitted or is corrupted. If the result is “yes” then the process proceeds to step 164 where a rescan of the coupon is performed, and then the rescan is confirmed at step 148. It can be appreciated that steps 148-162 provide a process loop for initiating one or more scans of the coupon until there is no missing data per step 162.

[0136] When step 162 determines there is no missing data, then the process continues to determine if this is a calibration coupon (step 166). If the result is “Yes” that the coupon is a calibration coupon, then the process proceeds to step 168 where a welder's coupon (step 168) is placed on the roller tray and then the process returns to step 146. It can be appreciated that steps 146-166 provides a process loop for continued determination if the type of coupon that has been scanned until the coupon is not a calibration coupon (step 166).

[0137] When the coupon is not a calibration coupon as determined in step 166, the process then proceeds to step 170 that confirms identification and data quality. After this confirmation, the process then confirms communication connection (step 172). In the exemplary, this can be accomplished by a handshake, which is an automated process of negotiation between two participants through the exchange of information that establishes the protocols of a communication link at the start of the communication, before full communication begins. Data from the V-card and the scan sequence performed on the welder's coupon (determined to not to be a calibration coupon), can then be compiled for transmission and viewing.

[0138] Utilizing the communication connection, the process then triggers an email, text, message or any other type of communication to the instructor, the welder and/or the third party evaluation (step 174).

[0139] After which, a link to a welder profile can be provided (step 176). The welder profile can then be provided to the welder details (step 178), which can then be provided to the stored data (step 110). It can be appreciated that the stored data (step 110) can include the welder details entered in step 100 and/or the additional welder details from step 178 that can include the data from the scan sequence.

[0140] As described above, the stored data can then be provided to the internet and/or network connected systems, and/or to the machine learning programming.

[0141] Referring to FIG. 7, an in use or a workflow of a process of the present technology is described which provides operation of the present technology. For exemplary purposes, the workflow process can include a set-up operation 180, a data acquisition operation 200 in communication with the set-up operation 180, an evaluation operation 242 in communication with the data acquisition operation 200, and an analytics operation 256 in communication with the evaluation operation 242.

[0142] The workflow process can begin with the set-up operation 180 where the process starts at step 182. After which, a Home position initialization process (step 184) can be conducted on the gantry to place the gantry in a Home position capable of receiving a coupon on the rollers.

[0143] The workflow can then continue to confirm a Wifi connection (step 186), and then to review portal connection (step 188). The portal can allow any authorized user access to the system and/or the data. For example, an instructor located remotely could access the welder data utilizing the portal operated by or stored in the computer system of the cabinet or on a remote computer system in communication with the cabinet. In the exemplary, the portal can include a user interface to access a welder certification profile including the results of the scan.

[0144] After step 188, the workflow can proceed to initiate the ultrasonic probes (U-Vision) in step 190, and then to initiate UT (step 192).

[0145] Welder's information can be provided, for example utilizing a V-card including the welder's details that can be read or inputted (step 197), and then the workflow can determine if this is a new welder (step 196). If the welder's information or the V-card data represents a new welder, then the workflow can proceed to step 198 to initialize welder details. The new welder details can then be provided back to step 186. It can be appreciated that steps 186-196 provides a workflow loop until the welder details from the welder's information or V-card is no longer determined as a new welder.

[0146] If step 196 determines that the welder's information or the V-card data is not associated with a new welder, then the workflow can then proceed to the data acquisition operation 200, and specifically to step 202 that confirms the identification (ID). The information from step 196 can be provided directly to step 202 in a same system or can be provided via the internet and/or network 114.

[0147] After ID confirmation, the user can then place a calibration coupon on the rollers (step 204). A print text (TXT) program can be initiated (step 206) on the calibration coupon, and position verification (step 208) can be operated. In the exemplary, the print TXT program can be a separate program or a subroutine that is can control the gantry, similar to a program for operating a 3D printer or a multi-axis Computer Numerical Controlled (CNC) machine. After step 208, the workflow can then determine a “Go” or “No-go” status (step 210) on the position verification. If a “No-go” status is determined in step 210, then the workflow returns back to step 206 until a predetermined position verification is provided to step 210.

[0148] When a “Go” status in step 210 is determined, then the workflow proceeds to placing a welder's coupon on the rollers (step 212). After which, a print TXT program (step 214) can be initiated on the welder's coupon.

[0149] The workflow can then proceed to step 216 where a scan sequence is initiated, including automatically positioning the gantry (step 218) and then placing or positioning the ultrasonic probes on the coupon (step 220).

[0150] After which, a water “ON” operation (step 222) is initiated that activates the liquid pump to provide water on to the coupon by way of the hose.

[0151] Then a rotation sequence is started (step 224) that activates the roller motor to rotate the coupon supported by the rollers. While the water is “ON” and the coupon is rotating, the workflow can then proceed to step 226 which starts the ultrasonic (U-Vision) acquisition. Upon one or more complete rotations of the coupon, the U-Vision acquisition is stopped (step 228). Thereafter, the rotation sequence is stopped (step 230) and the water is “OFF” (step 232).

[0152] Upon ceasing of rotation and water flow, the gantry is retracted to the Home position (step 234), thereby moving the horizontal drive member and its associated probes out of the way for removal of the coupon (step 236) from the rollers and consequently from the coupon receiving chamber.

[0153] The workflow can then proceed to step 238 to confirm if there is no missing data from the U-Vision. After which, a link can be sent to the welder, the instructor and/or the portal (step 240).

[0154] After step 240, the workflow can then proceed to the evaluation operation 242, and specifically to step 244 that reviews the portal connection. The information from step 240 can be provided directly to step 244 in a same system or can be provided via the internet and/or network 114. The portal can then be provided with welder level certification information or a welder certification profile including the results of the scan.

[0155] For example, a Level III solicitation (step 246) can be performed, followed by a Level III selection (step 248), and then followed by a Level III evaluation (step 250). It can be appreciated that any welder level class can be utilized in steps 246-250.

[0156] Next, a report is generated and formatted (step 252), and a link is sent to the welder, the instructor and/or the portal (step 254) that includes the formatted report.

[0157] After step 254, the workflow can then proceed to the analytics operation 256, and specifically to step 258 that stores the link and/or data from step 254 in a database for machine learning (ML).

[0158] After step 258, the data can then be provided to an analytics program or software package (step 260). For example, but not limited to, the analytics of the data can be processed by Power BI® (business intelligence) from Microsoft® that can provide a predictive analysis of advanced analytics to allow users to create predictive models from the data. It can be appreciated that step 260 can utilize a collection of software services, apps, and connectors that work together to turn unrelated sources of data into coherent, visually immersive, and interactive insights.

[0159] The analytics in step 260 utilizes machine learning algorithms for predictive modeling. The analytics can be local system based or cloud based, and be configured or configurable to provide visualized data directly to the welder (step 262).

[0160] Further, the analytics can be used for welder level evaluation (step 264), for example, if the welder meets the requirements for Level III certification. The analytics can further be provided in a link sent to the welder, the instructor and/or the portal (step 266). Accordingly, the analytics of the weld performed by the welder on the coupon can be available to any and all authorized people in or in almost real time. Therefore providing rapid quality or certification information of the welder.

[0161] It can be appreciated that remote 3rd party evaluation and reporting can be accomplished utilizing the link provided or the portal, along with onsite analytics of welder performance.

[0165] The instructions 314 may further be transmitted or received over a network via the network interface device 288 utilizing any one of a number of well-known transfer protocols (e.g., Hyper Text Transfer Protocol (HTTP)). While the machine-readable medium 312 is shown in an example embodiment to be a single medium, the term “computer-readable medium” should be taken to include a single medium or multiple media (e.g., a centralized or distributed database and/or associated caches and servers) that store the one or more sets of instructions. The term “computer-readable medium” shall also be taken to include any medium that is capable of storing, encoding, or carrying a set of instructions for execution by the machine and that causes the machine to perform any one or more of the methodologies of the present application, or that is capable of storing, encoding, or carrying data structures utilized by or associated with such a set of instructions.

[0167] While embodiments of the ultrasound-based welder qualification system have been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the present technology. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the present technology, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present technology. For example, any suitable sturdy material may be used instead of the above-described. And although automated rapid inspection and delivery of welder performance results during training in accordance with certification parameters have been described, it should be appreciated that the ultrasound-based welder qualification system herein described is also suitable for analyzing material of a tubular member utilizing ultrasonic technology and an automated system.

[0168] Therefore, the foregoing is considered as illustrative only of the principles of the present technology. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the present technology to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the present technology.
