The authors provide a short characteristics of the welding fumes composition. Basing upon the literature and their own data the authors compare the opportunities of applying various analysis methods for determining the composition and the structure of the solid component of the welding fumes – including the spectroscopic, diffraction, resonance, thermochemical ones – and give their comparative characteristics. The authors provide the research data for the welding fumes composition obtained by the photometric, thermogravimetric, IR spectroscopy, atomic emission spectroscopy methods. It has been established that welding the steel applied in the mining equipment production significantly increases the content of toxic substances in the welding fumes as compared to welding the construction steels. The authors make a conclusion about applying various complementing methods of analysis for the welding fumes study.
