Since a plasma torch can stabilize high temperature arc plasma by employing a shielding gas, it is widely utilized as a heat source. Gas Tungsten Arc (GTA) is the most widely employed type of the plasma torch. GTA enables to produce the arc plasma with high energy density. Therefore it is suitable especially for processes to require concentrating the heat input at a point but less effective for processes...
Energy source properties of gas tungsten arc (GTA) strongly depend on physical property of a shielding gas. For its low electrical conductivity, helium (He) is employed as a shielding gas for conditions requiring high productivity in GTA-welding process. However, the high cost of He limits its applications. Therefore, an alternative shielding gas with lower cost and better energy source properties...
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...
