A finite element simulation of the Tungsten Inert Gas (TIG) welding process is done by using the commercial used software MSC MARC to analysis the properties of stainless steel plates of grade SS-316 with the single pass. The thermal analysis is done with the MSC thermal solver with the element type Quad 4 which is having the single degree of freedom. The maximum temperature of the weldment is coming as 18000C which is the main factor for the change in the metallurgical changes and the changes in the mechanical properties of the material. In this paper the temperature profiles at the different location in the transverse direction from the weld centre line and the transient thermal histories are plotted which can be used for the evaluation of the mechanical properties of the structure. The welding heat source model which is used in the study is the Double Ellipsoidal Heat source model which is the latest heat source model in the welding simulation.
