Abstract

PURPOSE: To suppress the growth of crystal and improve low-temperature toughness, etc. of fusion metal by defining the spacing of the multiple electrodes directed to the inside of square groove and generating arc alternately from the respective electrodes.
CONSTITUTION: Current-supplying chips 2a, 2b kare held inserted into the square groove where low temperature steels 1, 1 are butted. Consumable electrodes 3a, 3b directing both fillet parts are alternately suplied at a short period from the respective chips 2a, 2b. The inter-electrode spacing of the electrodes 3a, 3b is set at 10 to 40 mm. The preceding beads 4a of sufficient penetration are formed to one fillet part of the first layer by the preceding electrode 3a, thence the succeeding beads 4B are formed for the other fillet part by the succeeding electrode 3b; At this time, part of the preceding beads 4a having held preheat are partly melted by the succeeding electrode 3b, whereby the coarsened crystals are fined. In a similar manner, the second and subsequent layers are welded to part the formation directions of the respective crystals, whereby low temperature toughness is provided.
