Abstract

PURPOSE:To continuously, quickly carry out the welding of such parts as relay, etc., which are weak against the mechanical shock, by interposing the holed interceptor between the welded material and the laser oscillator, on purpose to scan the laser ray. CONSTITUTION:The iron core 8, which is fixed to the plate 6 using caps 16, is hermetic-sealed by glass 7; the traveling contact spring 1 is attached to the back stock 4 which is welded to the cap 16 of the iron core 8; hereby, the contact gap 10 is formed between the spring 1 and the end face f the cap 15 constituting the stationary contact. The iterceptor 18 is made of board type member which is prepared by gold plating on aluminum, copper, etc., and is unabsorbing the laser ray; a through hole 19 is bored in the interceptor 18 which is arranged on the boack sstock 4 so as to exposed the weld zone of the cap 16 and the back stock to the laser ray. The laser beam 17 is focused and is made to sweep plural times along the sweeping line 20 passing through the center of the hole 19; hereby, the laser ray irradiates only the welding position 14, and the welding is finished.
