A literature analysis showed, that in the world there are not the welding additives, which is contain in own composition more than 0, 37% mass. N. The investigations of the welding joints of the austenitic cast steel 05Kh21AG15N8MFL with the nitrogen containing 0, 57% mass with using the available welding additives was provided. The technology of TIG welding with using two industrial welding wires Sv-10Kh20N18M3AFS (0, 24% N) and Sv-25Kh25N16AG7 (0, 10% N) was developed. It was obtain the defect-free welding joints, having a high rate of the mechanical properties, resistance to the pitting corrosion in 3, 5% NaCl, containing up to 0, 4% ferrite.
