Typically the Brazing Process: A Basic Format

Brazing is the procedure of joining similar or unlike metals by melting a new filler metal and disbursing it between them. Although several metals require different brazing methods, in each full case, the process remains the same. Below is an put together of this procedure from beginning to end:

Cleaning

Dirt, rust, as well as residue, can weaken the brazing joint by creating a layer between the bottom metal and filler sheet metal. Therefore, the base metal is thoroughly cleaned before it is brazed. Light rust can be removed with an acid pickle solution, while heavy rust can require filing or grit blasting. Before getting rid of rust with an acid pickle solution, residue and dirt are removed using a non-residue cleaning solution.

Fluxing

Because oxidization can weaken the brazing joint by developing a layer between the bottom part metal and filler sheet metal, flux is applied to typically the joint to prevent oxidization. Flux can be applied by hand, with an applicator gun, or through dipping the metal within liquid flux. The latter two methods are chosen for high-volume projects.

Flux is chosen based on the characteristics of the metal. For brazing stainless steel, a flux having low corrosiveness (also known as a chemical corrosion) is used. When a corrosive flux is applied, it could have the opposite of its intended effect, causing the metal in order to tarnish and the brazing joint to be weak.

Setting Shared Clearance

The strength of a set up depends in part on the outdoor patio between its work parts. In most cases, the strongest combined is achieved by setting up a clearance of. 0015″ inches. When the clearance is actually wider than this description, the strength of the joint may be reduced to the strength in the filler metal, which is less than the strength of the base metal.

Heating the Assembly

The fourth step in the brazing process is applying warmth to the assembly by inserting it a furnace, or by applying heat to the joint(s) with an acetylene torch. Each time a high temperature or pure setting (e. g. oxygen-free atmosphere) is required, metal is brazed in a furnace. When a warm and pure atmosphere isn’t going to be required, metal is often brazed by the torch.

Cleaning typically the Assembly

After it is brazed, the assembly is stripped of flux residue and oxide scale. Quenching the assemblage in hot water – especially while it is still hot rapid will remove most débordement residues. Bathing the assemblage in an acid pickle solution is the best way to remove oxide size.

Conclusion

Brazing is a simple course of action, but the requirements for brazing certain types and metals of assemblies can be complex. For this reason, most companies delegate to a metal treatment support when they need brazed assemblies.

Although the procedure above is true of most metals, it does not sign up for all metals. For example; brazing stainless steel – or any additional metal – in a machine furnace or controlled atmosphere furnace eliminates the need for flux. To learn about the brazing practice for a particular metal, contacting a new metal treatment service is the greatest option.
