Abstract
PURPOSE: To prevent direct an occurrence and growth of cracks caused by welding, thermal stress, etc., in the parent metal, by forming a thick part united in one body with the main body by performing a build up welding on the main body in advance, and then, by welding parts to this thick part.
CONSTITUTION: A build up welding is performed on the surface of a parent pipe 1 within the area which is a little wider than that of a welding part 3 for a support lug 2, and a thick part 5 united to the parent pipe 1 in one body is formed. When this part 5 is formed, the margin 6 of the thick part 5 is constituted so that it may be connected smoothly to the surface of the parent pipe 1, and the connected part is finished by means of grinder, etc. When the thick part 5 is formed in one body with the parent pipe 1, the support lug 2 is welded to the thick part 5. In this way, even when any cracks are generated at the margin 4' of the welded part 3, the cracks proceed in the thick part and no damage will be given to the parent pipe 1. The crack generated in the thick part is repaired during the inspection period.
