Abstract

To study the influence of welding parameters on arc efficiency during pulse TIG welding of aluminium and mild steel, the heat loss through radiation was collected from a coil placed around the arc and the heat loss from torch was measured through the water employed for its cooling. 'The investigations revealed that the welding parameters and material of the work piece have definite influence on TIG arc efficiency. Higher efficiencies are associated with the welding of aluminium as compared to that of mild steel.
