<P>PROBLEM TO BE SOLVED: To provide a weld portion repairing method which enables high-quality padding welding hardly generating melting shortage, undercut, and poor fusion to efficiently be performed when repairing the weld portion wherein members having different materials are welded and joined each other. <P>SOLUTION: In the weld portion repairing method for repairing the weld portion wherein a first member 1 requiring temper bead welding and a second member 2 not requiring the temper bead welding are joined each other, there are included a cutting process of forming a groove section by cutting sections containing a part of the weld portion, and a padding welding process of performing multi-layered padding welding to the groove section. The padding welding process includes a temper bead multi-layered padding welding process to the first member 1, and thickness of a padding layer based the temper bead multi-layered padding welding process is thinner at a lower layer section rather than that of an upper layer section. <P>COPYRIGHT: (C)2013,JPO&INPIT |
