| Research Abstract |
The deep penetration can be obtained in plasma welding under inert shielding gas. The good mechanical property can be obtained due to the inert shielding gas, too. But efficiency of the welding is not good. On the other hand, a high efficiency of the welding was achieved by using MIG welding. The arc in MIG welding becomes unstable. In order to improve the arc stability, the hybrid welding system by using plasma and MIG welding was developed. The control circuit was made to synchronize the plasma welding with the MIG welding. Arc phenomena were analyzed by using the circuit and by taking with high speed video camera. The conditions for set up and welding were specified.
