Authors reported already that the twin electrode switching TIG welding method was effective to increase welding speed in the welding of thin mild steel and copper plate. This method in which welding current is alternately switched to each electrode by the transister circuits is characterized by preventing the arc blow between the closely spaced two electrodes. In this report, the new method was applied to the welding of 3.2mm thick copper plate and the following results were obtained. 1) The critical welding speed at which acceptable beads are obtained is about 600mm/min. This speed is two times as fast as that of one electrode DCSP TIG. 2) The preheating by the leading electrode is effective under the conditions of closely spacing the two electrode and of selecting the welding current distribution ratio of the leading electrode larger than that of the trailing electrode.
