AISI310 is widely used in the manufacture of heat exchangers, radiant tubes, muffles, furnace parts, food processing equipments. Welding is widely used fabrication method in such type of industrial applications; but unfortunately welding induces few problems such as residual stresses and induced distortions. Residual stresses have significant effect on performance of the weld joint subjected to loading. The AISI310 is welded using matched filler material. Thus the weld joint consist of two different materials having different behavior under tensile loading. In this study residual stresses are estimated by using Labeas and Diamantakos formula and values are assigned as an initial stress in FEM of weld joint. The weldment specimen model is subjected to tensile loading and effect of residual stress on local yielding is investigated. The ANSYS is used for this purpose. The response of weld joint to monotonically increasing tensile load is determined experimentally by conducting the transverse and longitudinal tension tests on UTM. The stress-strain behavior of the weld joint is studied vis a vis virgin 310 stainless steel alloy.
