Induction Brazing: How Induction Brazing Works

Induction brazing is a process where two or more materials such as pipe are joined together with a molten space filler metal using an induction heating coil which delivers a very high temperature. The induction brazing process will involve temperature more than 840°F but still it is have to below the temperature of the material (such as pipe). By the induction brazing process the join materials will have very strong permanent attachment.

 

The technology of brazing process itself has developing nowadays. New products and techniques of this metallurgical joining are discovering to enhance the performance, quality and cost effective that includes induction brazing method. In the last decades, brazing products and methods have been developed, including oxygen-acetylene torches, controlled environment brazing furnaces and vacuum furnace brazing and induction brazing. Today, brazing is used in a broad range of manufacturing systems including refrigeration and air-conditioning, household utensils, tubular structures, automotive parts, tools and machinery, electrical components, nautical and aerospace equipment, farm implants, and business machines.

 

To get the best quality and best cost effective brazing result is to have a best heating technique to ensure the best flow of filler metal in between the join of the material. In today demands the brazing process will also involve in a production line which a unique of brazing method is necessary to achieve best quality and cost effective. Therefore a unique induction brazing is widely using in such work.

 

In induction brazing method temperature are usually reached in a matter of seconds for higher manufacturing productivity. The Induction Brazing Equipment method uses magnetism to induce electrical resistance to heat up the base material. Induction heating in induction brazing has proven an important tool in these joining processes. It allows for rapid localized heating, joining high-strength components with minimum loss of strength. An exact heat control in induction brazing allows the brazing process to be performed efficiently.

 

Induction brazing alloys melt at high temperatures and provide high strength joints that can resist reasonably elevated temperatures without failure. Many of the alloys used for brazing are presented in the form of wire, strip, powder and also washers or rings for induction brazing process purposes.

The design of the induction coil must be made to order to behavior of the metals and the dimension and shape of the joining parts. When using the induction brazing, special concern must also be given to the heating pattern; the method of pre-placing the joining alloy; the tolerances between mating parts; the thermal conductivity; and the expansion characteristics of the material to be joined.

 

It is important that when designing brazing process (such in induction brazing) to consider the join strength which to have the maximum strength. This can be accomplished, in many instances, by pre-placing the joining alloy in such a way that it will flow into the joint by gravity and capillary attraction, showing uniform and complete penetration by appearance of the alloy at the opposite end of the joint.
