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 45,60and 70is 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.
