Abstract

Predicting temperature field in a Gas Tungsten Arc Welding process is essential and precondition for any study of thermal or mechanical behavior of the weld. In fact, thermal, material proprieties and physical phenomena have to be taken into account in order to predict welding morphology, residual stresses and the final product quality of the weld. In the case of analytical studies, simulations are done with many simplifications that affect result precision. In this study, a 2D numerical model is developed by taking into account heat transfer and distribution of heat source. Gaussian distribution for heat source is presented and simulated by using Finite Difference Method (FDM) with explicit scheme. This method permits following the evolution of temperature field throughout the studied material during welding process. Also, operating parameters effects on melted zone such as current welding and shielding gas have been discussed.
