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 SUS 304 steel were assessed. The good prospects for application of laser-microplasma welding for joining thin stainless steels were confirmed experimentally. 6 Ref., 2 Tab., 10 Fig..
