High-strength alloy steels of 30KhGSN2A type are widely used in the manufacture of products that can bear signifi cant loads. In the thermally hardened state, this steel has a tensile strength of more than 1500 MPa. Depending on the product, it can be used in thicknesses from 2 to 15 mm and more. However, the use of such steels requires strict technical requirements for their heat treatment, creating diffi culties during the manufacture of products. Development of welding technology in the manufacture of products of 30KhGSN2A steel is currently relevant. In the present work, technological features of welding of high-strength alloy steels of 30KhGSN2A type are stated. 14 Ref., 6 Tabl., 6 Fig.
Keywords: high-strength steels, pulsed-arc welding, heat-aff ected zone, structure, mechanical properties, austenitic welding materials
