Abstract
PURPOSE: To make possible automatic welding without causing any defect in weld zone by heating the outside pipe surface of the weld zone to reduce the outside pipe diameter and make the clearance between the inside and outside pipes correct at the time of fillet-welding the pipe faying parts in an ocean structure or crane using pipes.
CONSTITUTION: If the clearance 4 between an inside pipe 1 and an outside pipe 2 is too large, weld beads 5 are put on the entire outside surface circumference close to the free end of the outside pipe 2 or the entire circumference is heated by a non-consumable electrode. As a result of this, shrinkage and falling occur on account of the heating, resulting in the decreased spacing of the faying parts and providing the clearance that permits automatic fillet welding. If the automatic welding is done in this state, the defect-free fillet welding 3 is obtained.
