The paper presents the results of an experimental study to determine the effect of the degree of plastic deformation of the low-carbon steel electrode wire (0.23% carbon) on the burning of an electric arc. Before testing, the wire samples were compressed to different degrees of deformation. During the study, the effect of the dispersion of the dislocation cellular structure of cold-deformed steel on the process of burning an electric arc was determined and the effect of the ferrite grain size was estimated. It was found that for an electrode made of low-carbon steel, the effect of resistance to the process of burning an electric arc from the side of ferrite grain boundaries with large misorientation angles exaggerates the effect of sub- and grain boundaries. The state of a solid solution acquires the effect of the presence of an additive contribution in the structure of steel sub- and grain boundaries.
