Notes:
A numerical model of time-dependent gas shielded metal arc is described, which wasdeveloped in order to make clear the kinetics of arc plasma together with metal transfer. It ispossible to calculate and visualize time-dependent temperature and fluid flow field of argonshielded metal arc plasma with the grow-up and the subsequent detachment of the liquid metal dropat the wire tip. Numerical calculation shows that the arc shape in globular transfer abruptly changesat the moment of metal drop detachment. Whereas, the spray transfer arc seems to be stable andalmost does not fluctuate with metal transfer
