On arc efficiency in gas tungsten arc welding [PDF]
Soldagem & Inspeção, 2013 The aim of this study was to review the literature on published arc efficiency values for GTAW and, if possible, propose a narrower band. Articles between the years 1955 - 2011 have been found. Published arc efficiency values for GTAW DCEN show to lie on a wide range, between 0.36 to 0.90.
