Abstract: An offline teaching device include an input unit that receives an operator operation, an acquisition unit that acquires three-dimensional shape data of a workpiece, an operation trajectory of the welding, and a scanning range of a sensor; a generation unit that generates three-dimensional regions to be scanned by the sensor based on the acquired scanning range and a scanning section; and a control unit that disposes at least one of the three-dimensional regions on the three-dimensional shape data of the workpiece based on the operator operation input to the input unit, and that creates and outputs, to a welding robot that performs the welding, a teaching program for scanning the three-dimensional region based on the disposed three-dimensional region and the operation trajectory of the welding.

Abstract: A bead appearance inspection device includes an input unit configured to enter input data related to a welding bead of a workpiece produced by welding, and a determination unit configured to perform an inspection determination related to a shape of the welding bead based on the input data. The determination unit determines which of a range of a value indicating a non-defective product zone, a range of a value indicating a gray zone, and a range of a value indicating a defective product zone a value obtained from the input data belongs to. The range of the value indicating the gray zone is between the range of the value indicating the non-defective product zone and the range of the value indicating the defective product zone.

Abstract: A repair welding segment detection method includes generating, based on a result of the inspection determination, shape mismatch data obtained by extracting a shape mismatch portion of the weld bead, dividing the shape mismatch data into N. where N is an integer of 2 or more, equally divided windows in a direction perpendicular to a welding direction of the weld bead, setting a shift region formed by i, where i: an integer of 1 or more, continuous windows among the N windows, separately calculating volumes of (N-i+1) shift regions obtained by shifting one by one the i windows forming the shift region in the welding direction, and determining that a shift region having a volume of a predetermined value or more among the calculated volumes of the (N-i+1) respective shift regions is a defective segment of the weld bead.

Abstract: A repair welding control device includes a memory that stores instructions and a processor that executes the instructions. The instructions cause the processor to perform acquiring information indicating a range of a defective portion in main welding of a workpiece, and determining a repair welding start point indicating a start point of repair welding and a repair welding end point indicating an end point of the repair welding such that a repair welding range includes all the range of the defective portion and a range wider than the range of the defective portion.
