A newly developed twin electrode switching TIG welding method has been applied to the welding of thin aluminum alloy plate. The new method has a characteristic of prevening the arc interaction by alternately switching the welding current to the each electrodes. In the welding of 4mm thick aluminum alloy plate (A5052), the critical welding speed of the new method is about 2m/min and is about two times as fast as that of a conventional one electrode DCSP TIG welding method. Furthermore, the new method can expand the suitable ranges of the arc voltage and the welding current. The resaon for the expanding of welding conditions is due to the reduction of the arc pressure that is about one-forth as low as the conventional one electrode method.
