| titleOfInvention | METHOD FOR PLASMA MULTIPLE ARC WELDING USING CONTINUOUSLY BURNING DC ARCS OF DIFFERENT POLARITIES |
| abstract | Multiple arc plasma welding is effected using continuously burning d.c. arcs of different properties where adjacent arcs have opposed polarity, using protective media (I) and a plasma-forming gas (II). All arcs are ignited between nonconsumable electrodes (e.g. three electrodes) and the workpiece; or some arcs are formed between electrodes and the workpiece while another arc is created between a consumable electrode and the workpiece. The ratio: prod. of the current of two adjacent arcs:distance between these arcs, is >=6.103 A2/cm. (I) is pref. CO2, Ar, a gas mixture, and/or a welding powder. (II) is pref. a molecular gas, esp. CO2, for normal polarity; inert gas, esp. Ar; or their mixt. Used partic. for the welding of low alloy- and stainless steels-, Al and Cu. The entire thickness of joints can be welded at speed previously unobtainable. |
