Approach to Evaluations of High Temperature Materials Processing from a Computational Simulation of Arc-electrodes System

摘要

The above numerical calculations showed that the calculated convective flow in the weld pool was principally dominated by the Marangoni force and the drag force of the cathode jet in argon arc. It was concluded that a balance of these driving forces could change the direction of re-circulatory flow in the molten anode and dramatically varied the weld penetration geometry.
