Abstract

PURPOSE: To obtain a weld zone of good quality extremely efficiently with the smallest number of passes by specifying the aiming position and spacing of both electrode wires and electric power source characteristics respectively at the welding of beads covering only the vertical plate to a lower plate in the multilayer weld zone.
CONSTITUTION: After ordinary welding of the 1st layer W1, two electrode submerged arc welding wherein at least one pole is not DC is carried out. At the welding of the 2nd layer W2 covering the lower plate B side, it is essential for facilitating the subsequent bead welding that the beads are as flat as possible and that the toes of weld are aligned. Therefore, the aiming positions of precedent and succeeding electrode wires 1, 2 are set respectively at distances d1, d2 from a vetrtical plate S, and the spacing d4 in the weld line direction W.D. of both wires is set at ≤30mm. Next, the beads of the smooth shape wherein there are no undercuts and the toes of weld are algined are necessary for the 3rd layer covering only the vertical plate S side. Therefore, the positions of the wires 1, 2 are set respectively remote from the plate S contrary from before and the spacing d4 is set at ≥40mm.
