The use of hybrid laser-arc welding laser + MAG for joining elements of large structures of stainless steel is a relatively new problem. The paper discusses the issues of technology of hybrid welding of austenitic steel X2CrNi18-9 and austenitic-ferritic steel X2CrNiMoN21-5-1 using a disc laser of 12 kW capacity. The technological conditions of hybrid welding with a full penetration of butt joints of steel with a thickness of 8, 12 and 20 mm, as well as T-joints with a butt weld with a partial penetration were determined. The typical defects in welds of high-alloy stainless steels, produced by hybrid welding, were indicated. 5 Ref., 20 Figures.
Keywords: hybrid welding, laser+arc, active gas, stainless steels, arc and beam parameters, location of sources, typical welding defects
