Determination of gas tungsten arc welding efficiencies

Experimental Thermal and Fluid Science, 1994
A combined experimental/computational technique for the estimation of gas tungsten arc welding (GTAW) efficiencies under quasi-steady conditions is presented. The instantaneous measurements of the weld pool length ahead of and behind the electrode are obtained from digitized free surface images, using a pulsed laser vision system.

Arc power and efficiency in gas tungsten arc welding of aluminium

Science and Technology of Welding and Joining, 2005
A calorimetric study of gas tungsten arc welding of aluminium is described. The present study comprised experiments in which autogenous welding runs were each made on a block of electrical conductor grade aluminium. The blocks were all approximately cubic in shape which, when combined with the high thermal conductivity of aluminium, ensured that their
