Treatment of Residual Stresses in welds in structural integrity assessments

摘要

This paper considers the treatment of residual stresses in structural integrity assessments of stainless steel butt and teebutt weldments. The background to the methodology is briefly reviewed together with its application to situations whereassurance of containment is required. Results are presented on the application of the method to an example reactorstructure subjected to a primary load in a corrosive environment. Conclusions are made as to the suitability of theapplication and possible benefits over existing methods.
