Abstract
The hard component of welding aerosol is one of the main hazards, which are encountered by those working with welding and related technologies. The investigations on this subject have been carried out for more than half a century. The size and dispersity of the particles are of particular interest among the properties and peculiarities of structure of hard component of welding aerosol, as these parameters define the ways of penetrating into a living organism. The present study examines dispersity of particles of hard component of welding aerosol by means of several types of equipment, involving different analysis principles. It was shown that the technique of preparation of a sample for analysis and peculiarities of equipment greatly influence the results. The morphology of particles was also examined. 20 Ref., 5 Figures.
Keywords: welding aerosol, hard component, dispersity, morphology, nanoparticle, agglomerate, laser granulometry, diffusion spectrometer
