Abstract :
Two distinctly different properties of an electric arc in an atmosphere of inert gas — a cleaning action of the arc when d-c reverse polarity is used on oxide-forming metals, and the resistance to current flow which is considerably higher when the electrode is positive — are described showing their effect on the application of the “Heliarc” welding process.
