Results of investigation of chemical composition and level of evolution of welding aerosols entering the air of working zone in flux-cored wire submerged arc and open arc surfacing are presented. Recommendations are suggested for protection of workers-welders and environment from welding aerosols.
Keywords: flux-cored wires, surfacing, welding aerosols, harmful elements, levels of evolutions, sanitary-hygienic recommendations, means of protection
