Effect of Welding Current on High Speed Welding Bead Formation in Tandem Pulsed GMA Welding Process

QUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 2005
In tandem pulsed GMA welding the stabilization of accumulated molten metal between the leading arc and the trailing arc, the presence of enough molten metal below the trailing arc, and the reduced velocity of molten metal flow towards the rear part of the weld pool are essential to improve the maximum welding speed.
