Abstract :
Samples of the solid component of welding aerosol (SCWA) obtained as a result of metal welding by two types of electrodes, ANO-4 and TsL-11, were characterized by elemental analysis, X-ray diffraction phase analysis, IR spectroscopy, and pH-metry. Both SCWA-ANO-4 and SCWA-TsL-11 samples purified the ozone-air mixture (OAM) with ozone concentration of 1.0 mg/m3 to the concentration values below 0.1 mg/m3 (maximum permissible ozone concentration, MPCO3).
