Brazing: Process And Advantages

Brazing: Process And Advantages

A technique used to successfully join dissimilar metals is called brazing. It is even possible to unite ceramics and metals through this technique. Copper manifolds, headers and headers are three types of products that may require brazed assemblies. It is a procedure that is often chosen over welding for several reasons. In fact, when it comes to brazed assemblies by Spinco Metal, you can easily argue the advantages far outweigh the disadvantages.

What is Brazing?

Brazing involves the joining of two metals using a filler metal. The filler metal acts as the medium through which the two parts are united. Although similar to welding, brazing involves much lower temperatures to melt the filler metal. It works within a flux during this process before it is cooled enough to unite the base metals it is joining together. It does not melt the pieces together but fuses them through the creation of a metallurgical bond between the surfaces of the two metals being united and the filler metal. This allows the metals to retain their integrity.

The process requires experience and the application of technological and human experience in fabrication. This is possible at several fabrication shops including that for brazed assemblies at Spinco Metal Products. Here they not only understand the necessity of providing a faultless product, but also realize the benefits of brazed assemblies.

Advantages of Brazing

There are many advantages to preferring to employ brazing over other techniques. Some have been noted above. The most common benefits are:

  • Firmer controls over consistency in joint quality

  • Produces a very strong joint

  • Produces a very clean joint therefore not requiring secondary operation

  • The result is an esthetically pleasing joint

  • Does not require such things as secondary finishing

  • Can be used to join dissimilar metals – in fact, brazing is able to attach almost any metal to any other metal with the exclusion, perhaps of non-brazeable metals such as titanium and zirconium

  • Can be used to unite dissimilar non-metals to metals

  • Less thermal distortion

  • Cost-effective method for both multi-and complex assemblies

  • Allows for such things as coating or cladding to protect the product

  • Easily adapted to mass production techniques and methods including automation particular small parts – through use of “furnace brazing”

When it comes to a choice between welded and brazed assemblies, brazing is becoming a preferred option for a variety of reasons. In addition to appearance, strength and ease of joining, brazed assemblies by Spinco Metal Products ensure the quality of the work can never be contested.
