Abstract
The paper deals with the influence of the intensity of evaporation of base metal and electrode wire elements, as well as shielding gas atmosphere composition on laser radiation propagation to the metal being welded in hybrid welding of aluminium alloys. Technological features of laser-MIG hybrid welding were studied, modes were selected and the obtained results were compared with consumable electrode pulsed-arc welding.
 
 
Keywords: laser-arc welding, aluminium alloys, pulsed arc, consumable electrode, hybrid process, butt joints, mode parameters, characteristic defects, mechanical properties
