description: In this study we consider the impact of adding nitrogen in the protective gas atmosphere on the microstructure and mechanical properties of metal deposited from austenite steel wire AWS 316LSi. Objectives of the study were: 1. Academic literature survey in the field of nitrogen containing steels, their microstructure, welding and deposition, and the effect of nitrogen on the properties of these steels; 2. Selection of parameters of electric arc deposition of samples with varying nitrogen concentration in protective gas atmosphere; 3. Analysis of nitrogen solubility in the investigated material; 4. Modeling of phase composition and mechanical properties of the deposited metal; 5. Assessment of macro- and microstructure of the produced samples; 6. Assessment of hardness and microhardness of the produced samples; 7. Analysis of the results of mechanical tests. The work was accomplished at the "Laboratory of lightweight materials and structures" at Peter the Great St. Petersburg Polytechnic University. During experiment we performed electric arc deposition of five "wall" samples with varying nitrogen concentrations in protective gas atmosphere. The influence of nitrogen on macro- and microstructure of the produced samples was investigated, the hardness and microhardness of the deposited metal wereÂ  evaluated, the calculation of nitrogen solubility in the investigated steel was made and the obtained parameters were compared with the limit equilibrium nitrogen concentration in the base metal at various pressure, the nitrogen influence on the various phases formation and mechanical properties of the deposited metal was considered. From the conducted research we can conclude that electric arc deposition surfacing is a perspective method for additive manufacturing and welding of nitrogen-containing steels.
