The welding process generates toxic fumes both from the metals involved and from the flux, if flux is present. Effective fume capture and removal coupled with efficient filtration is essential. Greater efficiency is required for welding or brazing operations where highly toxic contaminants such as chromium and cadmium fumes are generated. However all welding fume is injurious. AAF offers a range of filtration products which, when used in conjunction with effective hooding and ductwork, can provide a safe and hygienic working environment.
