Nano- and Microparticles in Welding Aerosol: Granulometric Analysis

Publication date: 2017 Source:Physics Procedia, Volume 86 Author(s): K.Yu. Kirichenko, V.A. Drozd, V.V. Chaika, A.V. Gridasov, A.S. Kholodov, K.S. Golokhvast The paper presents the first results of the study of the size of particles appearing in the welding process by means of laser granulometry. It is shown that welding aerosol is the source of nano-and micro-sized particles extremely dangerous for human and animal health. Particle size distribution in the microrange was from 1 to 10μm and up to 100%. It is shown that in 9 cases out of 28 with the use of various welding modes, welding rods and components the emission of aerosol with nano-sized particles (from 45.5% to 99.4%) is observed.
