At the same time, the gas flow acting on the keyhole is simulated by finite element method. The gas flow fields of pneumatic circumferential motion and pressure distribution nephograms around and in the keyhole are obtained. Analysis shows that when plasma is blown backwards i.e., in direction towards the trailing edge of the weld pool, plasma can be eliminated better.
