Brazing Galvanized Sheet Metal

Furthermore zinc provides electrolytic protection because it is anodic to iron.

Joining galvanized steel is normally done with one of a list of possible processes depending on application requirements. When heated or burned for the purposes of brazing poisonous and potentially lethal fumes are created.

Then clean the surfaces using soapy water or a degreaser. Cast iron galvanized nickel steel malleable iron. Position the metal as desired. Silicon bronze rod is great for galvanized sheet metal ercusi a.

6 4 1 the oxyacetylene torch is the heat source most commonly used for brazing. Bronze brazing welding rods. Brazing soldering galvanized sheetmetal techniques. Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal.

In most cases an overlapped joint. Brazing is distinguished from welding because it uses an intermediary material usually a copper zinc alloy to join the two metal pieces rather than melting the pieces. This process protects the surfaces of the steel from rust. Steel is often galvanized by dipping it into a zinc solution.

The usefulness of zinc coatings for rust prevention depends on the much slower corrosion rate of zinc as compared to that of steel. Zinc is electrochemically more reactive than steel.
