Welding fumes are composed of a mixture of metallic oxides, silicates, and other particles, depending on the materials being welded and the welding process used. Common sources of fumes include the base metals, filler materials, and coatings like paint or rust. When these materials are heated during welding, they can release toxic substances such as manganese, lead, and chromium, which can lead to serious health complications if inhaled over time. Therefore, ensuring proper ventilation is critical to safeguard the health of welders and those working nearby.
