An identifier management method is executed by a welding system. The identifier management method includes: acquiring information on identifiers of a plurality of original workpieces; randomly selecting any one of the identifiers of the plurality of original workpieces to be adopted based on completion of execution of a welding process using the plurality of original workpieces by the welding system; and setting the any one of identifiers of the plurality of original workpieces, which has been selected, as an identifier of the welded workpiece generated in the welding process.

An identifier output method is executed by a welding system. The identifier output method includes: acquiring information on identifiers of a plurality of original workpieces to which identification signs are assigned, respectively, the identification signs being assigned such that information on the identifiers are readable; selecting, from the identifiers of the plurality of original workpieces according to a predetermined rule, an identifier to be set for a welded workpiece to be produced by a welding process using the plurality of original workpieces; and after the selecting, in a case in which any identification sign among the identification signs assigned to the plurality of original workpieces is read by the reading device, outputting, as an identifier of the welded workpiece, the information on the identifier that has been selected to the reading device.

Reading device and method to read identification signs assigned to original workpieces for a welding process

A reception device includes: an image sensor that captures an image, and a reception unit configured to sample a plurality of pixels included in each of N (N being an integer greater than or equal to two) regions included in an imaging surface of the image sensor to receive, in parallel, N mutually different optical signals transmitted from a plurality of light sources.

A repair welding system includes an inspection device configured to inspect an appearance of a welded portion of a workpiece, and a robot control device that controls a robot configured to weld the workpiece. The inspection device determines whether there is a defective portion among welded portions of the workpiece based on a predetermined standard, and sets one of a plurality of defect ranks to the defective portion in a case that the defective portion is detected. The robot control device generates a repair welding program corresponding to the defect rank, and instructs the robot to execute, in accordance with the repair welding program, a repair welding on the defective portion to which the defect rank is set.

A repair welding inspection device includes a memory that stores instructions and a processor that executes the instructions. The instructions cause the processor to perform acquiring a second threshold, which is different from a first threshold which is a determination threshold for inspection of welding performed before performing repair welding, and the second threshold being a determination threshold for inspection of the repair welding, and performing inspection after the repair welding by using the second threshold.
