Elemental composition of WF particulates generated by RVSS and HVSS welding. RVSS and HVSS fume particulates were collected on to PVC filters (n = 4 for each fume type) and subjected to elemental analysis by ICP-AES following the NIOSH method 7300, which can detect over thirty different elements. ICP-AES analysis of the samples revealed the presence Fe, Mn, Cr, Cu and Ni as the major components (>99%) of the fume particulates. The concentration of each element was calculated as μg/mg of total metal and the mean concentration was determined. The weight percent of each element that composes the total metal portion of the fume was calculated and is graphically depicted.
