Hybrid laser-microplasma welding is one of the modern innovative processes of welding sheet stainless steels, allowing minimization of residual deformations, producing high-quality and durable joints. In this study, basic techniques of hybrid laser-microplasma welding were optimized, mode parameters were précised, and mechanical properties and corrosion resistance of the produced joints of SUS304 steel were assessed. The good prospects for application of laser-microplasma welding for joining thin stainless steels were confirmed experimentally. 6 Ref., 2 Tables, 10 Figures.
Keywords: laser-microplasma welding, SUS304 stainless steel, filler wire, rate of energy input, strength, elongation, corrosion resistance, hybrid effect
