Welding is one of the most important assembling methods which are widely used in different applications. In this work to obtain the residual stresses in the butt-weld joints of Fe3 410 WC steel plates, the thermo-mechanical finite element analysis of three dimensional has been performed by utilizing the MSC.Marc-Mentat software that is commercially available. The simulation of welding process was done by using the three dimensional finite element and Goldak double -ellipsoid heat source models. For the welding simulation there was considered a sequentially coupled thermo-mechanical analysis. The properties of the material depend upon temperature are specified. For the outward flux the heat losses of convective and radiations through boundary conditions are taken into account. The distribution of residual stresses and equivalent stresses are obtained in all directions. The welding process was simulated on nine different samples by utilizing the different welding parameters and it was shown that by giving different heat inputs, there are variations in the temperature distribution and residual streses.The maximum temperature and residual stresses are found by supplying the maximum heat input.
