WELDING METHOD AND WELDING SYSTEM

摘要

The movement of a single electrode (18a) by a welding robot system (a) is followed by the movement of a single electrode (18b) by another welding robot system (b). By constructing the single electrode (18a) of one welding robot system (a) and the single electrode (18b) of the another welding robot system (b) to perform welding simultaneously in the same direction on the same welding line, the degrees of freedom of the robots are not restricted, the available welding range becomes wide, and constraints on the posture of the robots are eliminated, compared with a case where a tandem welding-dedicated torch is used.
