Residual stress is one of the important factors that should be considered when assessing the integrity of welded structures because it is well known that residual stress may lead to failure in the weld joint. The residual stress around girth welds was studied with FEM using ANSYS (APDL). A coupled Thermo-Metallurgical-Mechanical analysis was carried out because the metallurgical analysis of the high strength steel used extensively in pipelines cannot be ignored. The final residual stress prediction using ANSYS was verified with experimentally to test the validity of the FEM model. The FEM...
