Abstract
Publications, describing the characteristic technologies of aluminium alloy welding by an arc constricted by high-velocity inert gas flow were analyzed. It is shown that plasma-arc welding (PAW) is further development of the process of nonconsumable-electrode inert-gas welding. It is established that during development of PAW of aluminium alloys, there was a transition from alternating sinusoidal current to reverse polarity direct current, and furtheron to variable polarity asymmetrical current with rectangular current waveform. A more promising direction of improvement of PAW equipment is transition from specialized power sources to modular design of PAW system, based on power sources applied for nonconsumable electrode welding and plasma modules. Further path of improvement of the processes of aluminium alloy PAW is combined or hybrid application of several heat sources, including the constricted arc and consumable-electrode arc. In the authors' opinion, hybrid consumable-electrode PAW with hollow anode and axial wire feed in the most promising variant. 41 Ref., 17 Figures.
