An x‐ray fluorescence spectrometric method is described for the determination of elements present in the fumes evolved during welding. Synthetic standards were prepared using salts of Si, Mn, Cr, Fe, Pb, Cu, Al and Ni for evaluation. The standards were mixed with boric acid in the ratio 1 : 1 and briquettes were prepared by the double pellet method. The samples were collected in filter‐paper discs by exposing them during welding. The average standard deviation of the method is about 7%.
