Extract

The technique of x-ray fluorescence is ideal for the analysis of metal fumes such as are produced in various welding and brazing operations. Although the constitution of welding and brazing fumes is dependent on the nature of the base metal, flux, and welding material used, they typically contain the oxides of iron, nickel, chromium, and manganese (stainless steel welding). The fumes are in the form of very small particles, usually 1.0 um, and are often agglomerated into long chains. Filter samples of these fumes, as are used in industrial hygiene monitoring, may contain 30-300 ug/filter of particles on one surface of a low-mass, 37-mm membrane filter.
