In the article it is shown that to improve mechanical properties and decrease indices of stress-strain state of welded joints of alloyed aluminum 1561 and 5083 alloys it is rational to apply hybrid plasma arc welding using arc of a consumable electrode, which as compared to traditional welding using arc of a consumable electrode allows reducing the electrode wire consumption by 10...30 %, input energy – up to 25 %, residual deformations – by 2...3 times, residual stresses – by about 20 % according to absolute value, as well as reducing burnout of such alloying element as Mg by 15...20%. 19 Ref., 6 Tabl., 9 Fig.
Keywords: hybrid plasma arc welding using consumable electrode (Plasta-MIG), pulsed arc welding using consumable electrode (MIG), surfacing welds, butt welds, strength, burnout of alloying elements, stress-strain state
