Abstract
Technological capabilities of the hybrid laser-plasma welding of aluminium alloys in comparison with plasma and laser welding were investigated. Properties of the welded joints made by hybrid method, as well as their microand macrostructure were investigated. It is shown that practical application of laser-plasma welding holds promise for thin-sheet aluminium alloys using lasers with a sharp-focused radiation spot.
Keywords: hybrid laser-plasma welding, aluminium alloys, laser radiation, diode laser, CO2-laser, filler wire, cleaning, heteropolar pulses, synergetic effect, mechanical properties, metallographic investigations, structure
