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.

Effect of the Fe Content on the Oxide Film Composition and Corrosion Resistance of Inconel 625: An XPS and Cyclic Potentiodynamic Polarisation Study

Surface and Interface Analysis, EarlyView.
ABSTRACT The present work focuses on investigating the effect of increasing Inconel 625 Fe content on the oxide film composition and corrosion behaviour through XPS and cyclic potentiodynamic polarisation (CPP) studies. Different proportions of ASTM A182 F22 steel and Inconel 625 were arc‐melted to achieve a range of Fe contents (2–15 wt.%) in the ...
