Residual Stress Simulation in Multi-Pass Weld of Stainless Steel Pipes
Multi-pass welds are used in pipes with stainless steel. The complicated temperature field and residual stresses in these welded structures are very important. The finite element method is used to simulate residual stress in multi-pass butt-welds in this paper. Element birth technique is implemented to model multi-pass welded 304 Stainless Steel Pipes. One-way coupled Thermo-mechanical analysis is adopted to calculate the residual stresses, that the structural analysis takes the temperature distributions as thermal input. The results provide reference for the structure integrity assessment of welded pipes.
