Abstract
PURPOSE:To reduce the welding defects through variation of the slope of the laser output waveform, by carrying out a successive on or off control for plural numbers of switching elements. CONSTITUTION:When a simultaneous on control is given to the switching elements 13a-13d at the time t1, the exciting lamps 16a-16d have a simultaneous flashing discharge by receiving the main discharging electric charge from the capacitor 12. Then a successive off control is given to the elements 13a-13d over the times t2-t5, and thus the supply of the main discharging electric charge is discontinued successively to the lamps 16a-16d to discontinue the flashing discharge of the lamps. Accordingly, the output of the laser rod 19 is nearly proprtional to the excited light volume supplied from the lamps 16a-16d, i.e., to the exited light volume from four lamps 16a-16d during the t1-t2 and three lamps 16b-16d during the t2-t3 respectively. In such way, the falling characteristics of the output waveform of the laser beam can be turned sharp or dull to improve the quality of the welding.
