Dec 10, 2017 · All 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 Welding Galvanized Steel -- SafelyThis is aggravated when welding conventionally hot-dipped products, since the edges frequently have excessively heavy zinc coatings. One solution is to separate the parts by 1/16 inch using wire spacers or fixtures which will hot dipped d steel pipe welding Welding Galvanized Steel -- Safely.Welding after hot-dip galvanising - RotocoatWelding hot-dip galvanised steel As a rule, welding hot-dip galvanised steel is no different from welding non-galvanised steel. Research has demonstrated that the mechanical properties of steel, whether galvanised or non-galvanised, welded or not welded, are identical. It is necessary to look at the area around the weld.
