One of the leading technological processes of manufacturing and repairing steel structures in various industries is welding, during which special wire is used. A necessary condition to achieving high quality of the welding wire is a providing required chemical composition, mechanical and technological properties. During cold plastic strain by drawing the strength of the silicon-manganese steel increases significantly, so to improve plasticity indicators it is exposing to intermediate heat treatment. But, prolonged dwell near the subcritical temperatures during such processing entails an increased consumption of energy resources. Possible ways of enhance the manufacturability production of the welding wire of low-carbon silicon-manganese steel were reviewed. The features of the formation of the structure and changes in the mechanical properties of low-carbon silicon-manganese steel after different modes of softening heat treatment were established. It has been shown that in silicon-manganese steel, if there are bainite-martensitic sites in the structure (~35 %), structural transformations begin at lower heating temperatures and accompanied by a change in the morphology of carbides. Based on received results of the structure formation for low-carbon silicon-manganese steel, the temperature-temporal parameters of softening heat treatment (annealing) with heating to temperature of 630 ± 10 °С and isothermal dwell during 2...2.5 hours were recommended. Specified processing mode is provides the formation of the spheroidized structure and increases the technological plasticity of the steel during subsequent drawing. Decision of the mechanical properties of the steel after heat treatment was showed that the strength indications decrease, and the plasticity increases to 40 %. Energy efficient mode of softening heat treatment is provides full compliance of the mechanical properties of silicon-manganese welding wire to the requirements of regulatory documentation.
