The zinc volatilizes and leaves the base metal adjacent to the weld. When galvanized sheet is resistance welded, the welding heat causes less disturbance of the zinc coating than the arc processes.See all results for this questionWhat kind of arc welding is used for galvanized steel?The amount of spatter produced when welding galvanized steel is slightly greater than when welding bare steel. The flux-cored arc welding process can be used as easily as gas metal arc welding for galvanized steel. It is recommended for the heavy gauges and on hot-dipped galvanized parts.See all results for this question

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.Welding Zinc, the Galvanized Steel Welding Hazard to 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.
