Abstract
Intensity if formation of welding aerosol and its composition in submerged arc welding using fused flux AN-60 containing fluoride added by different methods, e.g. by adding fluoride raw materials to the charge followed by its melting in furnace, or by heat treatment in the fluorine-containing gases, namely products of decomposition of ammonium fluoride NH4F, are studied.
Keywords: electric arc welding, welding fluxes, fluorination treatment, welding aerosols, sanitarian-hygienic characteristics
