Abstract
Main stages of development of equipment and technology of hybrid consumable-electrode plasma-arc (plasma-MIG) welding of aluminium alloys are analyzed. Main design solutions at development of torches for hybrid plasma-MIG welding are shown, i.e. transition from rod anode in hybrid torch plasma part to ring anode. Application of ring anode simplifies the design of hybrid torch for plasma-MIG welding and improves arc contact. The paper presents the advantages of the process of hybrid plasma-MIG welding with coaxial wire feed compared to traditional inert-gas consumable-electrode welding. 23 Ref., 15 Figures.
 
Keywords: hybrid plasma-arc welding, consumable electrode, coaxial wire feed, aluminium alloys, constricted arc
