Abstract

PURPOSE:To improve a welding quality by generating an arc by feeding a shielding gas between the zone to be welded of an A alloy and the electrode of an anode side and executing welding by projecting a laser beam. CONSTITUTION:A tungsten electrode 20 is arranged inside a nozzle 18 for the Al alloys 2a, 2b composing ths part 3 to be welded and the head 4 for laser welding is set up at the upper part of the part to be welded. First, an arc 29 is generated between an anode side electrode 20 and the welding part 3 with feeding an inert gas to the nozzle 18 inside. In this case, the positive ionized particle of a gas evaporates an Al oxidized film by decomposing it. The part 3 to be welded is then melted by a laser light beam under an inert gas environment to form a welding bead. The heat of the arc 29 is added and deep welding is executed after the evaporation of the Al oxidized film, so the welding quality is improved.
