In various examples, a computer-implemented method of generating instructions for a welding robot. The computer-implemented method comprises identifying an expected position of a candidate seam on a part to be welded based on a Computer Aided Design (CAD) model of the part, scanning a workspace containing the part to produce a representation of the part, identifying the candidate seam on the part based on the representation of the part and the expected position of the candidate seam, determining an actual position of the candidate seam, and generating welding instructions for the welding robot based at least in part on the actual position of the candidate seam.

The present disclosure teaches systems and methods for robotic welding of studs onto the surface of I-beams. These systems and methods will find industrial applicability in, for example, the steel erection industry.

A plate thickness test mechanism includes a detection section that detects an abnormality when a plate thickness is thinner than a desired plate thickness by a predetermined amount or more or thicker than the desired plate thickness by the predetermined amount or more, a determination section that determines whether or not the detection section functions normally, and a plate-shaped test jig that has a first plate portion having a plate thickness thinner than a predetermined specific plate thickness, and a second plate portion having a plate thickness thicker than the specific plate thickness. The determination section determines whether or not a plate thickness test is normally performed on the basis of a detection result of the detection section obtained when the detection section tests the plate thicknesses of the first and second plate portions by taking the desired plate thickness as the specific plate thickness.

Provided is an apparatus for coating a girth weld and a cutback region surrounding said girth weld, said apparatus having lateral travel at least equal to the length of the cutback region and circumferential rotational travel around the pipe. The apparatus can provide a multiple component coating accurately and safely, without the need for solvent flushing of the apparatus.

A soldering device includes: a soldering iron; a driver for moving the soldering iron; an input receiver for receiving an input of size information of a workpiece; and a controller for controlling the driver. The controller sets a coordinate of a specific position at a predetermined distance away from a soldering position based on the size information, sets, a speed of a tip at a distant position to a predetermined speed, and sets, an evacuation speed from the soldering position to the specific position to a low speed which is lower than the predetermined speed.

The present disclosure discloses a numerically-controlled plasma special-shaped cutting machine tool including a bracket, a cross beam, a feeding mechanism, a clamping mechanism, a gun head moving mechanism, a material conveying system, a material receiving device, a dedusting system, an electrical control system, and an outer cover. The present disclosure adopts plasma cutting, and the surface quality is obviously improved. Material conveying and cutting are performed by a predetermined program programmed in advance, and the dimensional precision of the machining is well ensured. Workers only need to place a workpiece material on the material conveying system, and the machine tool can perform automatic cutting. The labor intensity of the workers is greatly reduced, the cutting is continuously performed, and the machining efficiency is remarkably improved.

Systems and methods for real time feedback and for updating welding instructions for a welding robot in real time is described herein. The data of a workspace that includes a part to be welded can be received via at least one sensor. This data can be transformed into a point cloud data representing a three-dimensional surface of the part. A desired state indicative of a desired position of at least a portion of the welding robot with respect to the part can be identified. An estimated state indicative of an estimated position of at least the portion of the welding robot with respect to the part can be compared to the desired state. The welding instructions can be updated based on the comparison.

An apparatus (10) for joining a predetermined geometrical profile shape from a sheet material (SM) includes a positioning assembly (12) including a base member (14) and a frame (16) that is operable to receive the sheet material (SM), to configure the sheet material in a predetermined orientation and to linearly translate the sheet material along a process direction (20). A Z-bar (22) is configured to guide a first longitudinal edge (FE) and second longitudinal edge (SE) of the sheet material (SM) into adjacent alignment along the process direction (20). A welding and forging assembly (60) welds and then forges a seam between the first longitudinal edge (FE) and the second longitudinal edge (SE) of the associated sheet material (SM).

A welding apparatus has a guide rail arrangement with at least one guide rail attachable to a welding target. A carriage has a carriage housing and a rail follower assembly that is movably mountable to the guide rail arrangement for relative movement along the at least one guide rail. A feedstock source is disposed within the carriage housing and configured to deposit a feedstock material on a target surface of the welding target. An ultrasonic weld head is partially disposed within the carriage housing and has a sonotrode that extends toward the target surface so as to engage the deposited feedstock material and apply a normal welding force to the deposited feedstock material and the target surface. The sonotrode is operable to conduct ultrasonic vibrations into the deposited feedstock material and the target surface to weld the feedstock material to the target surface.
