Simulation of Welding Arc in Axial Magnetic Field

WANG Cheng1,CHEN Tang1,ZHA Jun1,BAI Bing1,2,XIA Weidong1(1.University of Science and Technology of China,Hefei 230027,China; 2.Full Dimension Power Tech.Co.,Ltd.,Beijing 100085,China)  
Numerical simulation of welding arc in axial magnetic field(AMF) at atmospheric pressure is performed with an ideal magnetic hydromechanics dynamics(MHD) model of coupled plasma and cathode.Hence the mechanism of the welding arc affected by the AMF is analyzed.The calculation results indicate that,with the increase of AMF,the cathode arc root and the arc column near the cathode shrink,the plasma temperature near the cathode increases,the arc column near the anode expands radically,yet the core temperature decreases;the current density and the pressure of the anode arc root are both torus in configuration,the heated area of the anode increases,the plasma temperature near the anode decreases,the maximum temperature of the anode surface decreases,a temperature flat appears,and the heat transferred to the anode increases.The AMF produces a "magnetic sucking" effect through inducing arc rotating near the anode by the Lorentz effect which will enhance upstream cooled gas flow.The effect of low pressure in plasma core,together with the cooling effect by upstream cool gas,will shrink the cathode arc root and the arc column near the cathode.The shrinkage of the cathode root enhances the cathode jet,as a result,the expansion of arc column near the anode is limited.
