Abstract

PURPOSE:To prevent the cracking of tack welding beads completely and eliminate the weld defects of a joint part by performing tack welding by utilizing the recess formed in a groove by gouging. CONSTITUTION:A root face 4 of a sufficient size is beforehand formed in the welded joint part of a single Vee groove of plate-like base materials 1. Next, the part to be tack welded in a groove 2 of the butt welded joint part is chipped off discontinuously by gouging, whereby a recess 3 is formed. After tack welding 5 for burying only the recess 3 is executed, the upper part of the tack weld beads is finished with a grinder to the same shape as that of the other groove face, thence continuous welding by perfect penetration is accomplished as regular welding to the single Vee groove.
