A new welding method has been developed to prevent arc blow from magnetic interaction between twin electrodes. In the new method the welding current which is supplied from a DC power source is alternately switched by transistor switching ciruits to each electrode.<BR>The results obtained in this study are as follows.<BR>1) Arc stability is maintained when the distance between the centers of the twin electrodes is 5-15 mm and the frequency of the pulse current is 10Hz-1kHz.<BR>2) When twin electeodes are used in close proximity to one another, the critical welding speed at which humping beads are induced is from two to three times as fast as that at which theyy are induced when the conventional twin electrode method is used.<BR>3) The critical welding speed of the new method at which acceptable beads are obtained is about 3 m/min for butt welding of mild steel plate in 1.2 mm thickness.
