The paper presents a review of studies on the influence of inoculation of dispersed refractory compounds into the weld pool on formation of weld metal microstructure in low-alloyed high-strength steels. Features of the process of primary structure formation are considered in the presence of refractory nonmetallic inclusions in the liquid metal, as well as on the interface of δ-dendrites and γ-phase. Possibilities of inoculant influence on the temperature range of bainite transformations, possibilities of formation of microstructural components with higher brittle fracture resistance, and improvement of weld metal toughness values are shown. 18 Ref., 5 Fig.
