Abstract

- The effect of airborne particulate matter on human health is today of considerable research interest. Essential parameters include elemental composition sampling with low pressure cascade impactors and analysis by particle induced x-ray emission spectroscopy (PIXE). It is shown that the aerosol generated by arc welding operations is several orders of magnitude denser than aerosols in ambient air. Most of the mass is found on particles between 0.1 and 1µm diameter, but the size distribution differs from one welding technique to another. The relative composition of the aerosol is found to differ significantly from that of both the welding piece and the electrode indicating the presence of fractionation of the type indicated in this work in designing electrodes and welding pieces to minimize the health hazards associated with the welding.
