Abstract

Welding is used in countless industries. The most common types are arc welding, resistance welding and gas welding.
Because of the high temperatures required to melt the metal, welding produces fumes that are potentially toxic. Of the pollutants found in these fumes, manganese oxide is of particular concern given the risk of severe neurological damage. Reducing fumes is therefore of critical importance in protecting welders.

The aim of this project is to review the state of knowledge about worker exposure to fumes from arc welding. The identification of factors having an influence on fume emission will lead to better protection of welders’ health.
