Brazing with induction heating


EFD Induction offers brazing in various important fields such as the automotive, aviation, electrotechnical and white goods industries. It includes brazing of aluminum, brass, copper, copper alloys, iron and cast iron, steel and stainless steel.


There are many reasons why using induction heating instead of gas for brazing is clearly beneficial. Induction transfers more energy per square meter than an open flame, resulting in faster heating cycles—put simply, you produce more components per hour.


The heat is also easy to check and adjust. You reduce the risk of overheating, which can lead to higher porosity and weaker joints. What's more, you reduce the risk of cold brazing as induction generates the heat in the base material.

Just as important, induction heating improves the working environment and safety. No gas needed, no open flame, no additional heating.

Induction coils

Having the right coil—and keeping it in the best possible condition—is critical to the efficiency of your induction solution. After all, the coil is the component that actually delivers the heat to the workpiece.


Our induction coil services cover all your coil needs: from coil design through to coil manufacture, installation, maintenance, repair and replacement.


Coil design

Correct coil design is essential to cost-effective induction heating. This service ensures you get design customized to your heating applications and materials. Which, in turn, means that you get the right heating patterns and your induction heating power supply delivers maximum output. You can use the service when introduction induction heating for the first time, or when upgrading existing coils. 


Coil database

Each EFD Induction coil is documented in a database containing all essential information. This makes it quick and easy for us to repair and replace your coils with constant quality. You can use the service when introducing induction heating for the first time, or when upgrading existing coils.

Induction brazing in the appliances industry

Refrigerators and freezers contain many compressor parts that need brazing. Dishwashers and washing machines, too, contain numerous heating elements. Our solutions for brazing white goods—include brazing of tube-to-tube, tube-to-block and tube-to-valve connections.


Induction brazing is easier than traditional gas flames methods. You don't need insulation shields. The work process is faster and the risk of error lower. Moreover, contemporary white goods include more plastic parts, which are sensitive to melting, further promoting the use of induction. 


Induction heating can also be used to braze faucets (tube to the socket, thread insert). Because the heat is accurate, controllable and repeatable, you get strong, leak-proof and corrosion-resistant joints.

Aluminum brazing

Induction brazing in the automotive industry

EFD Induction has a long track record in providing induction brazing solutions for the automotive industry. Here are some of the areas in which we are active:
  • Induction brazing of aluminum parts for air-conditioning systems, for example evaporator and condenser connections (tube-to-tube, tube-to-block, tube-to-tank)
  • Induction brazing of steel and copper components, e.g., brake linings, fuel injection pipes
  • Induction brazing of short-circuit rings for electric motors

Induction heating allows quick and accurate repetition of the desired heating cycle to the correct temperature. And the heat is easy to handle—no open flame to adjust, no need for insulation material to protect surrounding components. This, of course, promotes quality and uptime, and in the automotive industry there are numerous cases where induction has slashed brazing waste. 

Induction brazing

Induction brazing in the aviation industry

Within the aviation industry demands on temperature levels and heat supply are complex and precise. That’s why induction brazing is ideal —the heat is accurate, controllable and repeatable. 


Here are some typical uses of our equipment within the aviation industry:

  • Induction brazing of fan blades and blades for casings
  • Induction brazing of various parts for fuel systems, e.g. fuel connections
  • Induction brazing of various components in hydraulic systems

Induction brazing in the electrotechnical industry

Brazing electrotechnical components is tricky—copper isn’t just a good electric conductor, it’s also a good thermal conductor. You have to heat fast and accurately so the heat doesn’t spread and overheat other parts. And this is exactly what induction brazing is all about—fast accurate heat—and that’s why it is particularly suitable for electrotechnical brazing.


Most of our electrotechnical brazing solutions are used for:

  • Induction brazing of bars, strands, rings and wires in motors, generators and transformers
  • One-shot or segment brazing of short circuit rings
