Abstract

Formulation of welding process will help in basic design, modeling, simulation and analysis for the quick analysis where expensive commercial packages are not available. In this study a basic 1D modeling of the welding is done using the properties of Martensite steel. The temperature profile lateral to the welding direction is modeled for different boundary conditions (BC). Heat conduction & convection thermal stiffness matrices and thermal load are obtained using Galerkin’s approach. This simulation creates modeling of different heat flux loads like Cylindrical, Elliptical and Gaussian. Further, the shape changes in cross sections can be included a few are indicated. The discussion on various BC&
