Abstract

A three-dimensional mathematical model of rotational gas tungsten arc welding (GTAW) was established according to magnetohydrodynamics (MHD) theory, the welding arc of conventional GTAW and rotational GTAW were simulated by FLUENT to get the arc plasma’s temperature field, velocity field and the static pressure field. The results show that the centrifugal force has little influence on the arc plasma because it’s far weaker than the electromagnetic force, and the arc shape as well as physical quantity distribution of these two kinds of welding methods are essentially consistent.
