Brazing Sheet Metal

The filler metal is then brought into contact with the heated parts.

Brazing sheet metal.

Use the right brazing rod material for the metal used in your project. The oxyacetylene flame shall be directed mainly on the filler to minimize heat input to the base metal. It is melted instantly by the heat in the base metals and drawn by capillary action completely through the joint. The filler metal can be aluminum silicon brass bronze copper copper silver gold silver nickel alloy or silver.

In brazing the filler metal has a lower melting point than the adjoining metal. 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 as we ve seen uses the principle of capillary action to distribute the molten filler metal between the surfaces of the base metals. 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.

Brazing is a metal joining process in which two or more metal items are joined together by melting and flowing a filler metal into the joint the filler metal having a lower melting point than the adjoining metal. However the major differences are the following. Have you ever welded something so thin and worn out that all you do is blow holes in it. Wipe the areas on the metal pieces that will be joined with the emery cloth so the surfaces are free from dust and grease.

Brazing is similar to soldering but at higher temperatures. The forehand technique is usually preferred. In a brazing operation you apply heat broadly to the base metals.

Apply this paste to the areas on the metal pieces that will be joined using the brush. Use a torch that produces a high intensity flame. Mix a small amount of flux with water to form a paste. Proper temperature of base metal is indicated by a cherry red color.

In brazing and welding fabricators add a filler metal into the joint. This is how a brazed joint is made.
