Abstract
PURPOSE: To insert and weld stainless stell pipe on deposited layer and prevent stress corrosion cracking by forming the corrosion-resistant deposited layer on the outside circumferential surface of the welded joint of a stainless steel pipe and cutting away the joint part.
CONSTITUTION: The region where the cracking 4 of a stainless steel pipe 1 was detected and the outside circumferential surface of said pipe in the position where a repair metal member 6 is to be mounted are formed thereon with a build-up deposited layer 5 by metal of corrosion resistance higher than that of said steel pipe. Next, the welded joint part is cut away, after which a stainless steel pipe 6 whose diameter is larger than the outside diameter of the stainless steel pipe 1 and has better corrosion resistance than that of the steel pipe 1 is inserted. Next, both end parts of the steel pipe 6 and the deposited layer 5 are welded 7 by using the same welding electrode as the deposited layer 5.
