Why is it important to not weld galvanized metal?

Welding galvanized metal is particularly concerning due to the release of toxic fumes, specifically zinc oxide, when the protective coating is heated. This occurs because the galvanization process involves coating steel with a layer of zinc to prevent corrosion. During welding, the intense heat vaporizes the zinc, leading to the emission of harmful fumes that can pose significant health risks to workers if inhaled.

Avoiding welding on galvanized metal not only protects the welder's health but also highlights the importance of safety protocols in construction and maintenance. Other methods such as mechanical fastening or using a non-galvanized piece may be preferred to mitigate these risks. Understanding this aspect of working with galvanized metal is crucial for ensuring a safe working environment.
