Consider a TIG welding process where non-consumable tungsten electrode is in the vertical position. The electrode holds in a clamp and Initially maintained at a room temperature. The welding processes was is using the Iron specimen which has the melting point of 1540 °C. If the electrode tip which is in contact with the welded specimen having the same temperature of the specimen melting point and other side having the room temperature. Assume negligible heat loss from the electrode surface and temperature gradient along the radial direction is neglected. Consider a 1-dimensional steady state problem and find out the temperature distribution along the electrode length. Used the FVM method and discretised the computational domain into 5 subdomain. I Electrode Properties: Current = 225 amp; V = 16 V; Electrode dia = 3 mm; k= 175 W/(m.K); Electrode length= 10 cm.
