Abstract
The paper presents the results of investigations of dependencies of concentrations of noxious gases (carbon oxide and nitrogen dioxide) released into working zone air in covered-electrode manual arc welding on distance to welding arc under different ventilation conditions (with general ventilation, local ventilation and without ventilation). Respective analytical equations are derived that allow forecasting noxious gas concentrations in different points of the working zone depending on welding arc power.
