Abstract

PURPOSE:To improve quality and efficiency of welding by irradiating a laser beam to opposed face of an object to be welded to form a projection, contacting the objects electrically and welding them. CONSTITUTION:DC voltage is applied between a metallic piece 4 and a wire 5 to be welded from a power source 6. A laser oscillator 1 is excited and a laser beam is irradiated onto the metallic piece 4. The metallic piece is molten and a projection is formed on it. The wire 5 and metallic piece 4 are brought into contact by the projection. Then, charge of a capacitor 9 is discharged and the objects are welded by resistance heat energy generated at the contact.
