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