Abstract

PURPOSE: One side of base material is build-up welded, the other side is caused to generate compressive stress, thereby to prevent stress corrosion cracking.
CONSTITUTION: An build up welding 2 is deposited on the existing pipe 1 in the radialand longituidinal directions on such an area where stress corrosion cracking is expected to occur, such a place as the outer face of the pipe joining portion. The build-up welding, when cooling down, causes a contraction Δ1, generating inwardly directed force, to the effect such that the existing pipe 1 is bound by a hoop. Material of build-up welding 2 is, preferably, selected to have a thermal expansion coefficient less than that of the piping material 1.
