Abstract

This work uses computational thermomechanical model-based finite element analysis (FEA) to explore the effects of welding sequences on residual stresses that accumulate in the material and distortions of welded components, which are a direct outcome of residual stresses, the material microstructures, material properties, and eventually the fracture toughness. The consequences of the welding process are evaluated in this study in an austenitic pipe butt weld.

Keywords: residual stresses, distortions, finite element analysis, austenitic piping
