In this paper, the method of plastic stress analysis is applied to analyze the residual stress in the stainless steel weldings of stainless clad steel. As a result, the relation between welding conditions and the amount of residual stress was obtained, and the validity of these results was confirmed experimentally. As a result, it was recognized that large tensile stress occurs on the stainless steel welded surface, and the need was stated for providing stress relief to the welded parts of stainless steel in order to prevent stress corrosion cracking when they are used in the atmosphere in which such cracking is likely to occur. It was also suggested that this method of analysis would be of use in the analysis of contraction and deformation due to welding.
