摘要:Argon-shielded twin-wire indirect arc (TWIA) welding is a method with a high melting rate, high welding efficiency, low welding deformation and low penetration depth of the weld joint. In this paper, the arc behavior of the twin-wire indirect arc (TWIA) for current values of 100A, 150A and 200A and their influence on the welding process were discussed, and the reasons of the previously mentioned advantages of this welding method were analyzed. The plasma temperature was measured to verify the correctness of the simulation. The results indicate that the arc behavior is mainly controlled by the welding current, With the increasing current, the arc parameters in the anode and cathode regions significantly increase, whereas those in the arc column region vary by a smaller degree. The rate of increase of the arc parameters in the entire arc region is smaller than that of the welding current. The isotherm shifts toward the anode side and the shift of the isotherm increases when the welding current increases. The advantaged of TWIA welding was discussed according to the calculated result.
