Generation and Composition of Welding Fume

Welding fume purifiers are designed for the purification of fumes and dust generated during welding, polishing, cutting, grinding, and similar processes. They are also applicable to the recovery of rare and valuable metals. These systems effectively remove fine metal particles suspended in the air that pose significant health risks to humans. With features such as high purification efficiency, low noise, flexible operation, and a compact design, they are widely used in operations involving arc welding, CO₂ shielded welding, MAG welding, carbon arc gouging, gas welding and cutting, as well as other special welding applications.

As modern industry continues to evolve, processes such as welding, grinding, and cutting have become essential parts of manufacturing, and their usage has increased dramatically. However, despite their widespread use, the harmful impact of welding fumes on both human health and the natural environment has not been given sufficient attention. The composition of welding fumes is extremely complex. Studies have identified more than 20 different elements in the fume, with iron (Fe), calcium (Ca), and sodium (Na) being the most abundant, followed by silicon (Si), aluminum (Al), manganese (Mn), titanium (Ti), and copper (Cu). The primary hazardous compounds found in welding fume include iron oxide (Fe₂O₃), silicon dioxide (SiO₂), manganese oxide (MnO), and hydrogen fluoride (HF).

In addition to these solid particles, toxic substances such as acetaldehyde, abietic acid (rosin), isocyanates, nitrogen oxides, sulfides, and various hydrocarbons are frequently released during welding operations and become airborne. These substances can enter the human body through the respiratory tract and accumulate in the liver, lungs, cardiovascular system, and bloodstream. Long-term or repeated exposure to welding fumes can severely impact health, contributing to a wide range of occupational diseases, including lung cancer, asthma, eczema, bronchitis, skin allergies, and respiratory infections. In more serious cases, these toxins can disrupt the central nervous system, damage the digestive system, and lead to complications that may result in organ failure or death.
