Welding fumes

Welding fumes are a complex mixture of hazardous chemicals produced during welding.

The composition of welding fumes depends on factors, including:

  • the welding process,
  • the metal(s) being welded,
  • shielding gases or flux used,
  • the composition of the welding rod, and
  • any contaminants or coatings present on the metal being welded.

Workers undertaking welding processes are at risk of exposure to welding fumes. However, other persons at the workplace may also be exposed to welding fumes.

In Australia, the workplace exposure standard (WES) for welding fumes (not otherwise classified) has been reduced from 5 mg/m3 to 1 mg/m3.
