The paper aim is to study the influence of the current path in a metal work-piece of a welding Tungsten Inert Gas (TIG) configuration. A transient three-dimensional and magneto-hydrodynamic model of an interaction between an electrical arc and a metal work-piece is presented. The model couples the plasma and the metal domains and takes into account the metallic vapours presence.
