Brazing Sheet Metal

Brazing as we ve seen uses the principle of capillary action to distribute the molten filler metal between the surfaces of the base metals.

Brazing sheet metal. The oxyacetylene flame shall be directed mainly on the filler to minimize heat input to the base metal. Each of these setups has to be approached differently. In brazing the filler metal has a lower melting point than the adjoining metal. Home contact blog 888 272 9464 908 686 8401.

Mix a small amount of flux with water to form a paste. In brazing and welding fabricators add a filler metal into the joint. Use a torch that produces a high intensity flame. The filler metal can be aluminum silicon brass bronze copper copper silver gold silver nickel alloy or silver.

The forehand technique is usually preferred. My favorite is low temperature brazing using an alloy called hts 735 ii. Two brazing situations using the same materials. For over 25 years lynch metals has been north america s largest stocking distributor of aluminum brazing sheet stainless steel other metal alloys.

Silver brazing sometimes known as a hard soldering is brazing using a silver alloy based filler. There are a few different brazing systems out there. It brazes at low temperatures and makes it easy to connect all sorts of metals and the welds aren t brittle. Apply this paste to the areas on the metal pieces that will be joined using the brush.

Wipe the areas on the metal pieces that will be joined with the emery cloth so the surfaces are free from dust and grease. The brazing rod should be melted by the heat of the metal pieces being joined not by direct contact with the flame of the torch. Have you ever welded something so thin and worn out that all you do is blow holes in it. However the major differences are the following.

Did you want to learn how to work around that and deliver a solid re. Brazing means melting an alloy to join two metals. Crack in 90 10 cu ni metal plate due to stresses during silver brazing. In the first example watch for the angle of the torch.

6 4 3 a generous quantity of brazing flux applied to the filler rod and the joint area reduces zinc loss and produces sound joints. Therefore during the brazing process you should take care to maintain a clearance between the base metals to allow capillary action to work most effectively. Brazing is similar to soldering but at higher temperatures. Use the right brazing rod material for the metal used in your project.
