PURPOSE:To execute multi-point welding at a high sped by calculating in advance a moving time by a moving mechanism, and also controlling the start time of the movement and the energy charge by a command from an arithmetic control device which can compare the moving time and the energy charge time of a laser oscillator. CONSTITUTION:An electron gun 10 consisting of plural electrodes is placed in the center as an object to be welded, and a laser output part 23 which can be moved upward and downward, and to the right and left by ball screws 3, 4 and a pulse motor 12, etc. is installed to both its sides. As soon as it is started, read of a moving extent to an operation adjusting device is executed and the moving time is calculated. Subsequently, a correct condition is obtained by comparing the charge time with the moving time, and welding is executed. In this way, a loss of the energy charge time of a laser oscillator is eliminated, by which multi-point welding can be executed a high speed. |
