In the article it is shown that to improve mechanical properties and decrease indices of stress-strain state of welded joints of alloyed aluminium 1561 and 5083 alloys it is rational to apply hybrid plasma-arc welding using arc of the consumable electrode, which as compared to traditional welding using arc of the 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 the absolute values, as well as reducing burnout of such alloying element as Mg by 15−20 %. 19 Ref., 6 Tables, 9 Figures.
Keywords: hybrid plasma-arc welding using consumable electrode (Plasma-MIG), pulsed-arc welding using consumable electrode (MIG), surfacing welds, butt welds, strength, burnout of alloying elements, stress-strain state
