In order to clarify the formative mechanism of penetration geometry of anode in an arc melting process by using gas tungsten arc plasma, a numerical model is useful to understand quantitative values of the balances of mass, energy and force in the melting phenomena. In the present paper, the whole region of arc melting process, namely tungsten cathode, arc plasma and anode is treated in a unified...
Numerical modeling of free burning arcs and their electrodes is useful for clarifying the heat transfer phenomena in the welding process and to elucidate those effects which determine the weld penetration. This paper presents predictions for a stationary welding process by the free-burning argon arc. The whole region of the welding process, namely, tungsten cathode, arc plasma and stainless steel...
