Abstract

PURPOSE: To prevent the back side part from causing stress corrosion cracking by build up welding the back of the surface of a metallic structure exposed to a corrosive atmosphere by giving temperature difference from the surface and giving compression plastic deformation to the back side.
CONSTITUTION: An unpenetrated groove opening 3 is provided on the back of the surface of a product made of austenitic stainless steel which is in contact with a corrosive atmosphere. The groove opening 3 is build up welded as shown by 5 while water-cooling the surface 2 to cause temperature difference between the surface 2 and the back. By this operation, compression plastic deformation is given to the back side so that it becomes less than the limit stress of stress corrosion cracking or compression stress. In the case of butt welding, the back side is build up welded over a wider area than thermally influenced part of the butt welding while cooling the surface 2 exposed to a corrosive atmosphere. Thus, temperature difference is caused between the surface and the back and compression plastic deformation is given.
