Welding fume main compounds and structure

  • Nicolas Floros
Research Paper


Physical and chemical properties of materials cannot be predicted only taking into account their elemental composition. Their structure is critical information to make any assessment or to understand their properties. Health risks from welding fumes are usually based on elemental composition, not the compounds they are composed of. This sometimes leads to confusion or false assessments. A review of the main compounds of arc welding fumes, or the closest ones, in terms of both elemental composition and structure, is proposed.
