RESISTANCE WELDING CONTROL METHOD

PROBLEM TO BE SOLVED: To enhance the production efficiency by reducing the man-hour when releasing the prohibition and restarting the welding in a resistance welding control method for prohibiting the subsequent resistance welding when the number of striking Dc reaches the predetermined number of grinding of electrode Nr. SOLUTION: Even after the number of striking Dc reaches the number of grinding of electrode Nr, the remaining parts to be welded of a workpiece in process are welded, and the subsequent welding is subjected to prohibition Km. It is discriminated by the output of the workpiece welding completion signal Ws from a device for controlling the welding process that the welding of the remaining parts to be welded of the workpiece in process is completed. Thus, the prohibition is constantly output at the timing that the welding of the workpiece is completed. Thus, the welding after releasing the prohibition is always re-started from a new workpiece, and the re-starting man-hour is reduced. COPYRIGHT: (C)2009,JPO&INPIT
