Abstract

PURPOSE: To properly prevent the production of stress corrosion cracks by a method wherein when two members are joined, the inner circumferential surface temperature is made lower so that the residual stress in tension is reduced.
CONSTITUTION: A tubular member is heated to a high temperature as well as the temperature of its outer circumferential surface is kept higher than that of the inner circumferential surface. Then, the mating tubular member whose joint portion has a lower temperature than that of the inner circumferential surface is inserted into said member, and both the members are allowed to cool to join to eath other. Thereby, it is possible to reduce the residual tensile stress produced in the inner circumferential surface of the tubular member at the joint.
