COMPOSITION OF WISE FOR AUTOMATED ASSEMBLY Russian patent published in 2011 - IPC B23K35/30 C22C38/58 

FIELD: process engineering.

SUBSTANCE: invention relates to metallurgy and welding, namely, to welding wires used in automated welding of structures from nonmagnetic high-strength austenitic steel nitride in atmosphere of protective gases to be used in various industrial branches. Proposed wire comprises carbon, silicon, manganese, nickel, molybdenum, chromium, vanadium, nitrogen, sulfur, phosphorus and iron the following ratio in wt %: carbon - 0.04 - 0.08, silicon - 0.6 - 0.9, manganese - 3.5 - 4.0, chromium - 19.0 - 21.0, nickel - 15.0 -17.0, molybdenum - 2.4 - 2.8, vanadium - 0.01 - 0.3, nitrogen - 0.15 - 0.25, sulfur - 0.005 -0.010, phosphorus - 0.010 - 0.015, iron making the rest. Additionally said wire may contain zirconium in amount of 0.05-0.10 wt %.

EFFECT: lower magnetic conductivity of weld seam, higher rust resistance and welding properties.
