Numerical investigation on the residual stresses in welded T-joints made of dissimilar materials

This study used the Finite Element (FE) method to numerically analyze the thermo-mechanical behavior and residual stresses in
dissimilar welded T-joints. Residual stresses induced by the fusion arc-welding of steel joints in power generation plants are a
concern to the industry. The structural integrity assessment of welded structures requires the consideration of weld-induced
residual stresses for the safe operations in power plants, which may be compromised by their presence. Details on the used
thermo-mechanical FE model and the results analysis are herein presented.
