Abstract

A mockuptoproduct strategy was proposed to investigate the multipass welding residual stress in large nuclear structures First a mockup was manufactured and the temperature cycle during welding and residual stress after welding were obtained then the finite element FE simulation of welding temperature field and stress field for the mockup was performed using experimental results to calibrate the FE model and algorithms in addition a series of simulations on the mockup were undertaken to find the optimal model and efficient simulation methods finally the optimized model and efficient methods were adopted to simulate the welding residual stress of products Using the proposed approach the welding residual stress in the nuclear reactor pressure vessel RPV head with two Jtype welds was efficiently simulated and the stress interaction between the two Jtype welds were studied Research results suggest that the mockuptoproduct method can be applied to efficient numerical simulation of residual stress in large nuclear welded structures and simulation results indicate the stress interaction effect between two Jtype welds in AP1000 RPV head is not significant
