Abstract
A tungsten inert gas welding configuration including the weld pool is modeled. The model originality resides in the numerical and physical coupling between the plasma and the material considering metallic vapors. The necessity to consider one Marangoni coefficient function of the temperature to well describe the pool motions and the flow inversions is demonstrated by comparison with experimental measurement.
