Abstract

PURPOSE:To make possible welding of superior efficiency and the toughness of weld-heat-affected zone by employing an AC MIG welding method and performing multilayer welding of a plural pool system. CONSTITUTION:Preceding beads W3 are formed by the molten pool W1 relating to a preceding composite wire 1f, and the succeeding beads W4 are successively formed on the upper layer of the preceding beads W3 by the molten pool W2 relating to a succeeding composite wire 1r. Slag W5 is formed on the preceding beads W3 in front of the succeeding composite wire 1r, but since this slag W5 is thin, it is melted away without any problem by the arc of the succeeding composite wire 1r. In this way, the preceding and succeeding beads are formed approximately simultaneously by the respectively independent plural molten pools W1, W2 and the multilayer welding in one run is performed, hence the quantity of heat input is dispersed to the wires 1f, 1r and the low temperature toughness of the weld-heat affected zone is improved.
