The article presents the results of research of the phase identification and of the quantitative phase analysis of fume generated during Cold Metal Transfer (CMT), ColdArc and Metal Inert Gas / Metal Active Gas (MIG / MAG) weld brazing. Investigations were conducted for hot - dip coated steel sheets with zinc (Zn) and zinc-iron (Zn - Fe) alloy coatings. Arc shielding gases applied during the research-related tests were Ar + O2, Ar + CO2, Ar + H2 and Ar + CO2 + H2 gas mixtures. The analysis of the results covers the influence of the chemical composition of shielding gas on the chemical composition of welding fume.
