Abstract
The whole region of tungsten inert gas (TIG) arc welding, namely, tungsten cathode, arc plasma and weld pool is treated in a unified numerical model. Calculations have been made for stationary TIG welding in an argon atmosphere at a current of 150 A. The two-dimensional distribution of temperature and the geometry of the weld penetration is predicted.
