Abstract

The modes of electron beam, automatic and manual argon-arc welding of new corrosion-resistant steels hardened by various processes and filler materials were chosen; processing characteristics, mechanical properties and structures of welded joints were investigated. VNS-72 and VNS-73-Sh steels alloyed with carbon and nitrogen are superior to carbon-bearing alloys in the complex of mechanical and corrosion properties. Welded joints from VNS-72 steel are applied after full heat treatment of joints. Welding of parts from VNS-73-Sh steel is carried out both prior to strengthening heat treatment and in heat-treated state. Welding of VNS-63-Sh steel is carried out in the annealed state; besides heat treatment, welded products are subjected to cementation.
