Residual stress distributions for multi-pass welds in pressure vessel and piping components
- Edison Welding Inst., Columbus, OH (United States). Technical Div.
A welding simulation methodology is implemented and experimentally validated to predict residual stresses on multi-pass welds. The simulation involves performing thermo-elasto-plastic analyses using a consistent element activation approach in the mechanical analysis. A compendium of residual stress distributions in common pressure vessel and piping components is generated by using the multi-pass finite element methodology. Residual stresses are computed for circumferential girth welds on thin- and thick-walled pipes with various radius to thickness ratios. Both single- and double-V weld joints are investigated. Additional analyses are performed to evaluate seam welds and the effects of end restraint and hydrotest.
