Chuiko I. Development of alloy steel rod chemistry and thermomechanical treatment technology that provide a buildup of deflectivity during the drawing process of welding wire

Wire rod of alloy molybdenum, nickel, chromium, vanadium and other elements of electric welding purposes. Development of chemical composition and technological regimes weaken thermomechanical treatment rod of alloy steel welding appointments that enhance deformability during drawing of welding wire. Metallographic, electron microscope, electron microprobe, dilatometric, mathematical modelling and optimization. The kinetics of austenite transformation during continuous cooling. Thermokinetic diagrams are built. For the direct drawing of wire rod, alloy molybdenum, nickel, chromium, vanadium and other elements in the welding wire diameter up to 2,0 mm microstructure should consist of ferrite in the number of not less than 95% with the actual grain size of not less than 8 ... 9 facilities in accordance with GOST 5639. Conducted pilot-scale testing of wire rod processing. Yield of welding wire with a shiny copper coating is not less than 96%. Implemented. Metals, hardware companies.
