Welding headwear comprises one or more image sensors, processing circuitry, and a display. The image sensor(s) are operable to capture an image of an unpowered weld torch as the torch passes along a joint of a workpiece to be welded. The processing circuitry is operable to: determine, through processing of pixel data of the image, one or more welding parameters as the torch passes along the joint to be welded; generate, based on the one or more welding parameters, a simulated weld bead; and superimpose on the image, in real time as the torch passes along the joint, the simulated weld bead on the joint. The display is operable to present, in real time as the torch passes along the joint, the image with the simulated bead overlaid on it.

An additive manufacturing system includes an energy source and a material delivery device. The energy source is configured to direct an energy beam toward a component to form a melt pool. The material delivery device is configured to feed a wire toward the melt pool to deposit material on the component. In some examples, the material delivery device is configured to discharge a current to the wire to disengage the wire from the melt pool. In some examples, the material delivery device is configured to measure an arc voltage between the wire and the component.

A system managing a polishing state of tips of a welding gun of each welding robot installed in a production line of a vehicle includes: a robot controller storing tip polishing data including the number of polishing of the tips and a polishing amount of the tips generated after each tip dressing of the welding gun; and a server collecting the tip polishing data from the robot controller to store the collected data according to robot identification information of the robot and learning the store data through artificial neural network to generate reference data determining the polishing state of the tips corresponding to the robot identification information. The robot controller sets artificial neural network of the robot based on the reference data and determines whether a polishing state of the tips according to the number of polishing and the polishing amount of the tips is normal.

Provided is a welding helmet control device comprising: a welding sensor or a light sensor configured to detect presence and intensity of welding light; a controller configured to count presence, intensity, and elapsed time of welding light, detected by the welding sensor or the light sensor, and to determine welding intensity, weld time, resting time, and weld number; a memory configured to store the welding intensity, the weld time, the resting time, and the weld number; a display configured to display the welding intensity, the weld time, the resting time, and the weld number, stored in the memory; a shutter driver configured to drive a shutter liquid crystal display (LCD) to vary a darkness concentration under control of the controller; and a setting unit configured to receive a setting value and a manipulation command, set by a user, and to transmit the received information to the controller.

Gas-shielded arc welding in which the tip-to-work distance changes is configured so that fluctuations in welding current are curbed while arc length control is maintained. This is achieved with a corrected current calculating unit that includes a first controlling expression where a first gain G1 is multiplied by an instantaneous voltage error value that is the difference between an instantaneous output voltage setting value and an output voltage detection value, and/or a second controlling expression where a second gain G2 is multiplied by an average voltage error value that is the difference between an output voltage setting value and an average output voltage detection value of a pre-set period of time, determines an arc property gain G1 and/or G2 based on a torch position detection value determined by a torch position determinator, and calculates a corrected current based on the first and/or the second controlling expression.

The present disclosure relates to a portable production machine, a mobile terminal, a production system having a portable production machine and a mobile terminal, and a method for capturing data. According to aspects of the disclosure, on the production machine - which can be, for example, a welding machine or cutting machine - production data is automatically captured, organized into data sets, and converted into data set images, which are displayed on a display device. The displayed data set images are captured with a mobile terminal and transmitted to a central server. As a result, a plurality of production machines can be incorporated into a data system without the need for any changes to the hardware in the production machines.

A robotic welder includes one or more motors, one or more articulating arms connected to the one or more motors, one or more sensors configured to image a wear plate for determining welding locations for welding the wear plate to a blade of a machine, and an orbital welder to rotate a torch head for welding the wear plate to the blade.

A display system for a welding helmet that includes a darkening filter layer, a high-dynamic range (HDR) camera system to capture an HDR light field, and an optical image stabilization subsystem. Captured images are displayed on an HDR electronic display within the welding helmet without risk of overexposure of ultraviolet radiation to the operator. In some examples, dual electronic displays are used to display different HDR images to each eye of the operator.

Embodiments of welding and cutting systems are disclosed. A welding or cutting system includes a power source to provide electrical power for a welding or cutting process. The system includes a torch having a cryptographic device, and is to be used with the power source during the process and communicate with the power source. The cryptographic device is configured to receive an encryption key seeded by the power source during first time power-on initialization of the welding power source or after the torch is replaced. The cryptographic device is configured to store an unlock code associated with the power source, generate an encrypted message, which includes the unlock code, based on the encryption key, and communicate the encrypted message to the power source. The power source is configured to cease further operation unless the power source determines the torch to be a genuine manufacturer torch based on the unlock code.

A device and a method for welding a welding stud to a substrate are disclosed. A welding current is applied to a welding stud between the welding stud and the substrate, whereby a material of the welding stud and the substrate is partially liquefied. The welding stud is then immersed into the solidifying material of the welding stud or the substrate in order to create a bond between the welding stud and the substrate.
