Welding Galvanized Steel American Galvanizers AssociationAll grades of hot-dip zinc coated steels can be welded by oxyacetylene fusion welding. Preparation for welding is similar to that for welding uncoated steel. Because low travel speed is necessary for this process, which is necessary to bring the joint edges to the fusion temperature, the extra heat causes the zinc coating to be affected over a much greater area than when using faster welding processes.
