The object of the study is the welding shop, where manual and semi-automatic welding is used and there are no fixed working places. The authors present the results of numerical research of the distribution of the air parameters in the welding shop equipped with general forced ventilation. Calculations are made for the warm period of the year. The number and locations of supply and exhaust devices were accepted as constant, the angle of supply of supply air varied. The fields of temperature, air motion velocities and concentrations of pollutants such as manganese, aluminum, nitrogen and carbon oxides are considered. As a result of the analysis of engineering and numerical calculations, substantiation of the selection of the design scheme for the organization of the air exchange and air distribution is presented, and the parameters of the incoming air are determined.
