Abstract

PURPOSE:To prevent oxidation of a rear side effectively in making continuous welding by irradiating a laser beam by spouting inert gas to the rear side of material to be worked and preventing its diffusion by a shielding member. CONSTITUTION:In making welding work of a pair of materials to be worked 5, 5 placed on a jig 8, inert gas is supplied to the first and second supply pipes 6, 10 and spouted from an opening 3a of a holder 3 and a spounting nozzle 12.... A laser oscillator 1 is then operated, and at the same time, a table 7 is driven. The rear side of the materials to be worked 5, 5 irradiated and heated to raise temperature is covered by inert gas spouted onto this part and does not come into contact with the air and consequently not oxidized. Moreover, a shilding member 13 is attached to the second supply pipe 10 to control the direction of flow to prevent diffusion of inert gas.
