PROBLEM TO BE SOLVED: To provide a laser welding system for improving production efficiency.SOLUTION: A laser welding system has a plurality of welders; a laser oscillator; a switching device; and general control means. The general control means generally controls the welders, the oscillator, and the switching device, and comprises a storage unit storing current-carrying priorities, welder determination means, normal-completion determination means, and priority determination means. The welder determination means performs determination processing for determining the welder having the highest current-carrying priority among the welders that have output welding request signals as an active welder. The normal-completion determination means determines whether weld processing by the active welder has been normally completed. When a determination result of the normal-completion determination means is YES, the priority determination means sets the current-carrying priority of the active welder to a lowest priority, advances current-carrying priorities of the welders lower than the current-carrying priority of the active welder, and maintains current-carrying priorities of the welders higher than the current-carrying priority of the active welder, With this configuration, it is possible to improve production efficiency.SELECTED DRAWING: Figure 4 |
