The predicted residual stresses in this dissimilar weldments with the yield limits and self-balanced and these stresses were in good agreement with experimentally obtained stresses. Thermal stresses which were predicted in compressive nature at weld zone due to improper thermal cooling cycles. The peak temperatures were predicted at the HAZ of Inconel 718 than the HAZ of AISI 316. Five different points were taken to measure the stresses in order to validate the results obtained from FE results. Thermally induced residual stresses in the Inconel 718 and AISI 316 dissimilar joints were measured experimentally by using X-ray diffraction technique. The suitable boundary conditions such as heat transfer coefficient as well as radiation considered for predicting accurate results. The elemental birth and death techniques were considered for modeling the filler element. In this paper, the temperature gradients and also thermally induced stresses were predicted numerically by performing coupled thermo-mechanical analyses. The finite element analysis is the most effective numerical tool for predicting temperature distribution, residual stresses along with thermal distortions in welded joints.
