Manual arc welding: Chromium VI compounds and more besides in the welding fumes
Up to the formation of chromium VI compounds: In manual arc welding, the kind of hazardous substances in the welding fumes is very much determined by the metal of the core rod and its covering. Particularly hazardous are high-alloy rod … >> more
Factors for the amount of welding fumes
How much welding fumes created in any welding work depends on many factors: Not only the method and the materials used influence the amount of welding fumes. The welding fumes emissions, expressed in mg/s, are smaller than the smoke and … >> more
