Abstract
Metallography reveals the correlations between the amount, size, and morphology of ultrafine particles in welding materials (flux-cored and composite wires, coated electrodes, and agglomerated fluxes), as well as the processes of formation of exogenous crystallization centers in the welding pool that facilitate the structure modification and promotion of processing and working properties of deposited metal. The phenomenological model of the nucleation on ultrafine exogenous refractory chemical clusters is developed on the basis of the experimental data and on the existing view of the kinetics of fast physicochemical processes in the welding fire point.
