Galvanized Steel. The process of welding galvanized steel is commonly found in the metal fabriing industry. Many welders usually weld galvanized steel at some point in their career; and in doing so they may experience galvanize poisoning or metal fume fever. Galvanize poisoning is a condition that results from the over exposure to zinc oxide.

Zinc oxide (ZnO) is not a porous oxide, but forms a dense protective layer that cannot be penetrated by oxygen or water. Iron can be coated with a thin layer of zinc in a process called zinc layer quickly reacts with oxygen to become zinc oxide. This layer protects the zinc underneath it from being further oxidised.

Burning zinc looks similar to burning magnesium. It flares off white zinc oxide smoke and leaves heavy soot like yellow and white oxide deposits where the smoke cools. In the metal working shop we are often exposed to small amounts of zinc smoke without ill effect. It is common in brazing, casting brass and ocassionally welding.

Zinc is more corrosion resistant than steel in most natural atmospheres, the exceptions being ventilated indoor atmospheres where the corrosion of both steel and zinc is extremely low and certain highly corrosive industrial atmospheres. For example, in seacoast atmospheres the corrosion rate of zinc is about 1/25 that of steel.
