CONTROLLER FOR WELDING ROBOT

摘要

PROBLEM TO BE SOLVED: To provide a controller for a welding robot capable of instructing an appropriate welding route to the welding robot even in a temporary welded part. SOLUTION: The controller is provided with a route storing part 111 for storing a teaching route for a welding part, a decision part 112 for deciding whether a detection result by a detector 13 corresponds to the temporary welded part or not, a result storing part 113 for associating the detection result by the detector 13 with a decision result by the decision part 112 and storing it, and a correction part 114 for correcting the teaching route which is stored in the route storing part 111 using the detection result and the decision result stored in the result storing part 113. When the decision result stored in the result storing part 113 corresponds to the temporary welded part, the correction part 114 does not use the detection result corresponding to the decision result and the constant number of the detection results before and after thereof for the correction of the teaching route.
