摘要：
Oxygen is mixed with another gas to form an auxiliary gas that will permit a welding of zinc-plated steel sheets (3a and 3b) without producing blowholes. An oxygen (O.sub.2) gas cylinder (4a) is provided in addition to an argon (Ar) gas cylinder (4b), for forming the mixed auxiliary gas, and the argon gas and the oxygen gas are mixed in a mixer (6) before being supplied to a machining head (7) and jetted onto a machining spot (9) through a nozzle (8). The oxygen oxidizes the zinc of the zinc-plated steel sheets (3a and 3b) to produce zinc oxide and zinc peroxide, to thereby prevent evaporation and minimize spatters, and thus permits a laser welding with a minimum generation of blowholes.
