Induction heating is ideal for brazing of short-circuit rings

Induction brazing

ENRX offers brazing in various fields, such as the automotive, aviation, electrotechnical and white goods industries.

Induction heating explained

Induction heating is ideal for brazing applications

What is induction brazing?

Brazing is a materials joining process that uses a filler metal (and usually an anti-oxidizing solvent called flux) to join two pieces of close-fitting metal together without melting the base materials. Instead, induced heat melts the filler, which is then drawn into the base materials by capillary action.

What are the benefits?

Join a wide range of metals, even ferrous to non-ferrous
Heat only narrowly defined areas
Ideal for integration into production lines
Correctly brazed joints are strong, leakproof and corrosion resistant
They are also very neat, usually requiring no further milling, grinding or finishing

Where is it used?

ENRX brazing systems can be used for virtually any brazing task. To date, our systems are typically used in the electrotechnical industry to braze generator and transfomer components like bars, strands, rings, wires and SC-rings. They also braze fuel pipes as wellas AC and brake parts for the automotive industry.The aeronautics sector uses induction to braze fan blades, blades for casings, and fuel and hydraulic systems. In the houseware industry our systems braze compressor components, heating elements and faucets.

Induction brazing of short-circuit rings

What equipment is available?

Our brazing solutions usually include an ENRX mobile Minac or stationary Sinac system. Both product families offer a wide range of output powers and frequencies, together with automatic matching and robot compatibility.

Induction brazing of short-circuit rings
Bars of silver filler about to be heated for brazing bars to a short-circuit ring. Once heated to the correct temperature, the filler will appear to “float” on the surface of the metal, before being drawn evenly into the joint by capillary action.
Usually, the strongest joints are made by allowing just enough space for the filler metal to flow into the joint area. Wider spacing will generally result in a weaker joint.
