Best Practice Guide for Welding Hot Dip Galvanized SteelsNearly all hot dip galvanized steel fabrications involve welding of the steel elements. Occasionally there are defects related to the welding, either aesthetic or structural. This guide describes the best practice welding of steel that is to be hot dip galvanized, shows some common visual defects in the welded Difference Between Galvanized and Hot Dip Galvanized Jul 02, 2019 · The key difference between galvanized and hot dip galvanized is that most galvanized materials have a smooth and sharp finishing, whereas hot sip galvanized structures have a rough finishing.. Galvanization is a process of preventing metal surfaces from corrosion.After the completion of galvanization, we say that the surface is galvanized if it is done via the usual procedure.

    Zinc, which comprises the hot-dip galvanized coating is very high on the Galvanic Series (Figure 2), which means it will be anodic to most other metals. So, when hot-dip galvanizing is connected to other metals , the zinc coating will not only sacrifice itself to protect the underlying base steel, but also try to protect the other connected metals.
