Authors reported already that the twin electrode switching TIG welding method was effective to increase welding speed in welding of thin mild steel plate. This method is characterized by preventing the arc blow between closely spaced two electrodes. In the method, welding current is alternately switched to each electrode by the transistor circuits. In this report, it was applied to the welding of 0.8mm thick thin copper plate and the following results were obtained. 1) The critical welding speed at which acceptable beads are obtained is about 9m/min. That speed is two times as fast as that of the one electrode DCSP TIG. 2) The lead pool width becomes narrower than the trail pool width. However, the trail electrode sufficiently forms a large weld pool as same as the pool width of one electrode DCSP TIG by the preheating effect of the lead electrode.
