Welding fumes are primarily composed of:

Welding fumes are primarily composed of microscopic particles produced during the welding process. When metals are heated to high temperatures, they can evaporate and form fine particles that are much smaller than what can be seen with the naked eye. These microscopic particles can include a variety of metals such as zinc, manganese, and lead, as well as other compounds that can be harmful when inhaled.

Due to their small size, these particles can penetrate deep into the respiratory system, leading to potential health risks for welders and those nearby. Proper ventilation, respiratory protection, and other safety measures are essential to minimize exposure to these harmful substances. Understanding the composition and potential dangers of welding fumes is critical in any safety training related to welding operations.
