Abstract

Metal transfer phenomena in high current GMA welding with several kinds of shielding gas have been systematically investigated with high-speed cinecamera. Typical transfer modes are classified into four types, depending on the welding current: globular transfer, axial spray transfer, swinging spray transfer, and rotating spray transfer. The dependence of the transfer mode as welding current can be explained by the instability of melted electrode using numerical modeling based on MHD theory.
