These materials feature additions of copper, nickel, and chromium that help improve the atmospheric corrosion resistance of the steel.
When you arc weld galvanized steel, the heat produced by the welding arc is high enough to vaporize the zinc coating. This results from the variation in boiling points between zinc (lower) and steel. Proper precaution is needed when handling these coated metals, as their fumes can lead to serious conditions like the Metal Fume Fever.Welding of Coated Steels : Total Materia ArticleWelding of zinc-coated steel can be done, but specific precautions should be taken. When galvanized steel is arc welded the heat of the welding arc vaporizes the zinc coating in the weld area. This is because the boiling point of zinc is below the melting point of steel. The zinc volatilizes and leaves the base metal adjacent to the weld.
Those welding stainless steel appear to be more at risk. Ultimately, welders are undoubtedly at risk of developing a number of horrible long-term health effects, but it is also true that if the proper safety procedures are followed, these risks will be dramatically curtailed.Welding, Cutting, and Brazing - Occupational Safety and inch3 Safety Concerns when Welding Galvanized Steel Construction can be a safe occupation when workers are aware of the hazards, and an effective Safety and Health Program is used.
