Abstract
An X-ray fluorescence technique (XRF) was developed for the analysis of welding and brazing fumes. Welding or brazing fumes were collected on six standard filter cassettes and examined by electronmicroscopy and X-ray diffraction to assess the particle size and deposition. Samples were then analyzed by XRF, ashed, and analyzed by atomic absorption (AA). Samples were also analyzed by inductively coupled argon plasma emission spectroscopy (ICP). An XRF standardization method was developed using laboratory generated fume samples. Field samples were obtained at three welding shops, and samples were analyzed by XRF, AA and ICP. Results between the three methods were in good agreement. The author concludes that the XRF technique is suitable for fume analysis, although a more adequate standardization procedure is needed.
