Abstract

This paper provides approximate expressions for through-wall welding residual stresses in dissimilar metal nozzle butt welds of pressurized water reactors. An idealized shape of nozzle is proposed, based on which systematic elastic-plastic thermo-mechanical finite element analyses are conducted by varying the thickness and radius of the nozzle and the length of the safe-end. Based on the results, a through-wall welding residual stress profile for dissimilar metal nozzle butt welds is proposed by modifying the existing welding residual stress profile for austenitic pipe butt welds in the R6 procedure.
