Abstract: Gas Tungsten Arc GTA welding has long been used to join newlinematerials in aerospace marine and nuclear power industries Variations in the newlineheat input during GTA welding of stainless steel have significant effects on newlinethe weld pool weld bead geometry microstructure and hardness of the weld newlinemetal and the heat affected zone Apart from melting the metal heat input newlinecauses liquid motion in the molten weld pool which in turn affects the bead newlineshape and size Since 1941 the simple conduction based numerical model for newlinewelding problem has been improved by the proper selection of assumptions newlinematerial properties boundary conditions and inclusion of all possible driving newlineforces for weld pool convection To obtain results for real welding problems newlinethe assumptions have been minimized at various stages The developments in newlinethe computer hardware industry during 1980s have accelerated the progress newlineof modeling of welding Axisymmetric newline
