Does galvanized welding really exist or are you referring to an axle
galvanized after it was welded?

Welding temperatures are higher than the melting point of zinc, and zinc is
consumed or highly altered during any welding process. It also produces
toxic fumes that cause weld fume fever. Galvanizing is done after welding,
either on virgin metal, or a redip after welding repairs.

Zinc melts at 419.5, and iron at 1535. Steel is iron with other elements
added, and can be heated to over 2,000 degrees for tempering purposes. At
that temperature, the zinc would be burned off, or assimilated into the
metal.
