Abstract : Welding is widely used procedure for fabrication of joints and structures. This method has largely been developed by experiments; i.e., trial and error. The problem of large temperature gradient, residual stress, and distortion in structures due to welding is important to control, mainly in industries where the components are expensive. Simulation of welding process by finite element technique is a cost effective method for the understanding and analysis of the process. In this paper, shielded metal arc welding of SS304 plates of dimension 140x6x150 􀝉􀝉􀬷 is studied. The finite element analysis of temperature distribution in three different v-groove angle configuration of 45􀯢,60􀯢and 70􀯢is performed using MSC Marc 2013 software. The analysis include a finite element model for thermal welding simulation. It also includes a moving heat source, material deposit, temperature dependent material properties and transient heat transfer. Element birth and death technique is employed for the simulation of filler metal deposition. This reduces the computational time and memory space required. The peak temperatures attained at different points during deposition of weld bead from the weld centre line is compared. It is predicted that the groove angle has an significant effect on the magnitude of peak temperature. The temperature distribution that occurs during welding affects the material microstructure, hardness and residual stresses present in the material after welding. Keywords - AISI 304 SS, SMAW process, Finite element method, Birth and death technique, temperature distribution, groove angle configuration.
