Thermal effects of gas tungsten arc (GTA) and temperature field from it on workpiece (copper) and shielding gas type, is the main key of analysis and process optimization for GTAW, that main goal of this paper is defined about that. Energy source properties of GTA strongly depend on physical property of a shielding gas. In this paper, carbon dioxide (CO2) was used as an alternative gas for its low cost. The basic energy source properties of CO2 GTA were numerically predicted ignoring the oxidation of the electrodes. It was predicted that CO2 GTA would have excellent energy source properties comparable to that of He, Ar GTA.
