Abstract

PURPOSE: To form weld joint free from welding defects by providing a separate groove for introducing welding arc on the bottom of a V-groove of a pair of welded tubes the weld zones of which are butted through a V-groove.
CONSTITUTION: Tubes 10, 12 to be welded are butted through a V-groove 14, and a root gap 16 is provided between the tubes 10, 12 to be welded. Several tack beads are provided on the bottom of the V-groove 14, and thereby fixed temporarily through the root gap. Then, a new groove 14a is provided to introduce another welding arc. Since this groove 14a is U-shaped, the welding arc reaches the groove 14a.
