Health Hazards of Laser-Cutting and Welding Fumes

Welding fumes refer to solid microscopic particles generated during welding processes that remain suspended in the air for extended periods. These fumes are a major occupational hazard, polluting the workplace environment and posing serious threats to workers’ health. Inhalation of such fumes can lead to a range of occupational lung diseases, including pneumoconiosis.

In response to these challenges, Wuxi BONRXIN Environmental Technology Co., Ltd. has developed a series of fume purifiers specifically designed for the welding industry.

Compared to other types of industrial dust, welding fumes are particularly harmful due to their extremely fine particle size, which allows them to penetrate deep into the human respiratory system. Moreover, these fumes often exhibit high concentration levels, strong adhesion, and active surface properties. As a result, they are not only inhaled in large quantities but also tend to accumulate in the lungs, where they act as physical antigens. This continuous stimulation of immune responses in the affected organs may eventually cause cellular and tissue damage.

In addition, welding fumes often consist of heavy metal oxides, which can trigger toxic biochemical reactions once absorbed into the body—further damaging various organs and systems.

Beyond the threat to individual workers, welding fumes also represent a serious environmental concern. In many industrial settings, especially in regions where environmental awareness remains low, such fumes are inadequately treated or even discharged directly into the atmosphere. Ventilation systems may only offer partial filtration, failing to meet environmental standards.

The primary components of these fumes—heavy metal oxides and salts—are highly toxic and bioaccumulative. Once released into the environment, they may enter the food chain, posing long-term ecological risks. While certain plant species can absorb and neutralize these substances, this capacity is limited. When environmental emissions exceed natural absorption thresholds, the result may be ecological damage with irreversible consequences.
