【 摘 要 】

The analysis of literature data on the weldability of nitrogen-containing austenitic steels with high equilibrium nitrogen concentrations (0.4-0.6) is performed, and the results of studies of the structure and phase composition and mechanical properties are given for Cr-Mn-Ni-Mo-N welded joints with nitrogen concentration ∼ 0.5% obtained by laser welding (for thin sheet metal) and argon arc and manual arc welding (for hot rolled metal with a thickness of up to 20 mm)
