Abstract

PURPOSE:To manufacture a stainless steel tube joint which can prevent a stress corrosion cracking without requiring a post treatment, by previously performing build-up welding with a anticorrosion metal on the internal circumferential surface of the edge of the coupling part of a stainless steel tube, and then by performing butt welding at the tube end. CONSTITUTION:Over the entire internal circumferential surface of stainless steel tube 1 extending from the tube end by length (l), built-up part 2 made of anticorrosion metal of thickness (q) is provided by welding. After the build-up welding, shot peening or roll work is carried out at build-up part 2 and its circumference. As a result, layer 3 given the residual stress of compression is formed on the surface. The edges of this tube 1 and tube 1A of the same structure are formed and butted for coupling at weld zone 4 of low-carbon stainless steel, thereby obtaining a tube joint. Of this tube joint, the metallurgically sensitized part generated in the formation of weld zone 4 is covered with build-up parts 2 and 2A, so that stress corrosion cracking is prevented.
