HYBRID PLASMA-ARC WELDING WITH A FUSIBLE ELECTRODE, ALUMINUM ALLOYS, WELDING PRODUCTIVITY, ELECTRODE WIRE CONSUMPTION, WELDED JOINT STRENGTH The object of the study is the technological principles of improving the productivity of welding aluminum alloys, the quality and operational characteristics of welded joints using an automated process that combines a powerful concentrated energy source of a plasma jet with the thermal energy of a melting electrode arc. The purpose of the work is to expand the technological possibilities of obtaining high-quality joints from aluminum alloys and to create a complex of equipment for hybrid plasma-arc welding with a fusible electrode (PAW-MIG). Based on the results of the literature review, tasks were formulated, the solution of which will contribute to the industrial spread of hybrid PAW-MIG welding, as a promising high-performance method of joining aluminum alloys. The welding equipment for the automated PAW-MIG process has been improved and the design of the anode of the plasma part of the hybrid torch with increased operational reliability and resource has been proposed. PAW-MIG welding modes of aluminum alloys 1561, 5083 and 7075 with a thickness of up to 8 mm have been established, which ensure a high level of quality of welds and mechanical properties of welded joints. For PAW-MIG welding of aluminum parts with a thickness of 5 mm, the possibility of increasing the speed of the process 1.67 times higher than during arc welding with a fusible electrode in argon of the material of the same thickness (MIG) has been determined. The technological possibility of PAW-MIG welding to reduce electrode wire consumption by more than 40% compared to MIG welding has been proven. Product Description popup.authors Kvasnytsky Victor V.
