Abstract

PURPOSE:To prevent the generation of constriction of weld beads and obtain continuous weld beads by blowing a control gas to the molten metal pool formed at the start of welding, and performing welding while pressing the melten pool in the welding advance direction. CONSTITUTION:In synchronization with welding start time, blowing of a control gas 32 from a gas nozzle 30 toward a metal pool 28 is started. This pool 28 is pressed in the welding advance direction shown by an arrow D. This results in that the pool 28 is controlled flat and the generation of constriction as in the prior art in the weld beads formed in the weld start position is obviated.
