Medical studies indicate that the welding aerosols are one of the leading causes of occupational diseases welder, such as pneumoconiosis, etc. From the point of view of industrial safety is monitored only permissible concentration of hazardous substances included in the welding fumes. However, these data do not provide a complete picture of the impact of these substances on the body, a more important indicator is the mineral form of localization elements especially in the solid component of welding fumes, as well as their morphology, structure and dispersion. The authors present the results of a study on the morphology, structure and dispersion of the particles of the solid component of the electrodes for welding aerosols with different coatings. The characteristic relationship between composition and morphology, as well as between the particles and the nomenclature of view coverage.
