Welding is an industrial process that involves melting two pieces of metal together. Welding also produces harmful fumes and gases that can be hazardous to the health of the welder and others in the area. Weld fume hoods are a critical safety device that can help to protect workers from harmful fumes and gases.
Welding fume extractors or welding fume hoods are devices that remove harmful fumes from the air around a welding operation. Welding fumes are a mixture of gases and particles that are released when metal is melted and fused. These fumes can contain a variety of hazardous substances, including metal oxides, nitrogen oxides, and carbon monoxide. An evaluation in 2019 by IARC shares that welding fumes and UV radiation from welding are classified as carcinogenic.
Welding fume extractors work by drawing the fumes away from the welder's breathing zone and into a filtration system. The filtration system removes the hazardous substances from the fumes, and the clean air is then returned to the work area.
