The thermodynamic model of the formation of welding aerosol is proposed. The thermodynamic parameters of chemical compounds and aerosol phases are calculated. A program is proposed for the numerical calculation of the level of generation of various elements with the variation of the parameters which control the welding conditions. The results are compared with the literature data.

Solid ingredients of welding fumes can find application in manufacturing different components of welding equipment. Thus welding nozzles applied for gas-shielded welding have ceramic metal plugs which isolate welding torch nozzle from current conducting parts. TCCA as well as metallurgical sludge are applied in construction materials production, road construction, as coloring ingredients for decoration materials, in agriculture (soil deoxidation, mineral fertilizes).
