  author={Kehai Li and Jinsong Chen and YuMing Zhang},
Double-Electrode Gas Metal Arc Welding, referred to as DE-GMAW, is a novel process which decouples the melting current into base metal current and bypass current by adding a bypass torch to a conventional GMAW system to establish a bypass arc. This makes it possible to increase the melting current while the base metal current still be controlled at a desired level. Experiments have been done to find the conditions which can assure a stable bypass arc be established/maintained between the… CONTINUE READING
