HSL Laboratories Research Report from 2000 (2000/15) which set out to re-evaluate the reliability of EH54 methods for assessing exposures to welding fume.
The report concluded that while chemical composition of welding fume can be influenced by welding parameters, the variation was relatively small at <20%. Voltage was the variable parameter which exerted the greatest effect on chemical composition.
Results obtained from studies on Stainless Steel and Mild Steel were similar. This confirms the summaries of other research projects where it was found that in fact the ‘consumables’ contributed the majority towards welding fume.
