Abstract

PURPOSE: To suppress the occurrence of cracking and the propagation of cracks by performing build-up reinforcement of weld in the position slightly deviated from the central part of weld metal in build-up reinforcement of weld of the weld metallic part in a welding groove part.
CONSTITUTION: Base metals 1, 1 are butted, and weld metal 2 is built-up, whereby the base metals are welded. At this time, the central final solidification line 4 of the weld metallic part 2 is formed roughly perpendicularly along the wall thickness direction of the base metals 1. Thence, reinforcing overlaying 5 is provided in the position deviated slightly from the central part of the weld zone, that is, the central final solidification line 4 of the weld metal 2. With tubular materials or the like, it is deviated by about 2W3mm. Thereby, the lines 4 are made curved and discontinuous without the formation of the parallel lines 4 in the wall thickness direction, and the occurrence of cracking and the progression of its propagation along the solidification line are effectively suppressed.
