Welding aerosol as the source of dangerous for health technogenic nano- and microparticles: electronic and microscopic analysis

The first results of research the morphological and material structure of welded aerosol particles are given in work. It is shown that morphologically particles represent the hollow and integral spheres, sometimes covered with easily chopping off cover. Also objects of other form - ovals, polygons, needles meet. Fragments of cover of hollow spheres have the size to 10 microns (PM10) and uneven edges that does them and nanodimensional particles by components of welded aerosol most potentially hazardous to the person’s health. It is established that aerosol particles generally consist of Fe> Mn> Zn> Ti, but also the minor components Si, Cl, Zr, Co, Cr, Br, Al, Ca, Mg, K, C, S was meet.
