Abstract
Investigation results are presented on dependence of the concentration of harmful materials in the work zone air in manual rutile-cellulose electrode welding upon the distance to the welding arc under different ventilation conditions (general, local and without ventilation), as well as analytical dependencies of the concentration of harmful materials at different points of the work zone upon the intensity of formation of welding fumes and power of the welding arc.
