Abstract

PURPOSE: To shorten the working time and restrict runaway phenomenon, by welding with two welding heads from the both ends of multiple spot work successively to the middle, shifting one head to the middle, then subsequently welding while moving in the same direction.
CONSTITUTION: All spot rows of multiple spot work W are divided into two groups, and welding is started simultaneously with right and left welding heads from the corresponding spot (a or e) of row L1 and row R1 at the both ends of the work W. For example, when starting spot-welding from L1a and R1a, the both welding heads are moved toward the middle of the work W in the direction of arrow S. By welding an arbitrary number of spots by this preliminary process, one head is moved to a next spot R3a, while the other head is moved to spot Lna corresponding to R3a in the middle spot row in the left spot group. After welding the both spots at the same time, the remaining spots are welded, for instance, by moving the both heads in the same direction as shown by the arrow of broken line. In the case of work having an odd number of spot rows, the final one spot row is welded by a single head.
