Abstract

PURPOSE:To carry out laser welding satisfactorily by a method wherein electroless nickel deposition of suitable thickness is applied to a case and a cover and gold plating is applied to the parts other than those to be welded. CONSTITUTION:Before a base itself 4 and a cover itself 8 are welded, electroless nickel deposition film of 2-3mum thickness is formed on the base itself and that of 6-20mun thickness on the cover. Gold plating is applied to respective parts of the base itself and the cover other than the parts to be welded and laser welding is carried out while the laser power is controlled to approximately 3.8X10<8>J/mm.<2>. With this constitution, because gold plating layer 6 is climinated from the parts irradiated by laser beam 9, reflection of the laser beam is reduced and the welded parts are easy to be fused, so that satisfactory welding can be carried out.
