The concentration of ultrafrne particles at welder’s workplace was investigated. It is confirmed that ultrafrne particles with diameters < 100 nm are generated in welding and enter the workplace zone. Also, it is found that the concentration of ultrafine particles depends on the composition and diameter of a welding electrode as well as on the distance from the welding shelter zone. It is advisable to continue studies on the regulation of ultrafine particles, generated in welding of different types.

Key words: ultrafine particles, welding electrode, welding aerosol
