Abstract

Annotation. For the introduction of new technological processes in the welding industry, high-quality surfacing and welding wires are required. In the process of its production, the initial billet is successively subjected to cold deformation and annealing, while changes occur in its structure that affect a number of mechanical and physical properties of the material. Methodology. The methods of raster microscopy for the analysis of microstructure, mechanical tests, measurement of coercive force are used. Purpose of the study. Determine the effect of cold deformation and intermediate annealing on the structure, magnetic and mechanical properties of low-carbon steel. Results. The dependence of mechanical properties, coercive force, grain size and the number of special boundaries on the cold-deformation modes and annealing of low-carbon steel is established. Practical significance. The use of the value of the coercive force Hc as a monitoring tool allows controlling changes in the structure and mechanical properties of the billet during the whole technological cycle of manufacturing low-carbon welded wire in production conditions.
