Abstract: 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.
