What Is Induction Brazing?

Brazing with induction generates an electromagnetic field in a work coil that induces currents in the conductive material of a workpiece placed within or near the coil. Friction from these currents elevates the temperature of the workpieces and filler to be brazed.

What Benefits Does Induction Brazing Offer? 

  • Efficiency: Induction generates heat only in the portion of the part needed for brazing.

  • Repeatability: You can count on a precise, consistent quality braze every time.

  • Easy integration into a lean manufacturing process

  • Safety: No open flame or hot furnace

  • Small footprint: Frees up valuable factory floor space

Brazing Copper and Brass ValvesBrazing Copper and Brass Valves

To braze various copper and brass assemblies for a valve manufacturer; they are looking to replace their torch heating process with induction

Brazing Steel Fittings & Tubes (Hydraulics)Brazing Steel Fittings & Tubes (Hydraulics)

Braze steel fittings and tubes in an atmosphere to make hydraulic fittings within a targeted heating time of under 150 seconds.

Brazing Both Ends of a Steel AssemblyBrazing Both Ends of a Steel Assembly

The client wanted to braze both ends of the part concurrently within their time requirements. Induction met the client’s time requirements and is often faster than other heating methods. With induction there is no open flame and with induction’s instant on/off capabilities, it introduces less heat into the work environment.

Steel Brazing Applications

Induction brazing is the ideal technique for joining steel parts where welding is not suitable. A well-designed induction brazed steel joint provides many benefits including part geometry integrity and lower part stress. Carbon and stainless steel have high resistivity – they couple well to induction energy and heat easily. However, they have poor thermal conductivity so the induction brazing of steel parts should not be rushed. With steel, it is important the heat is given time to soak through to the joint surface for proper flow and wetting out of the braze material.


Steel, Copper and Brass Brazing

Induction brazing is an excellent method of joining parts made of dissimilar metals. Applications with mixed metal joining include steel-to-copper, steel-to-brass and brass-to-copper. With these materials, it’s all about timing. For a successful brazed joint between different metals it is critical that both metal surfaces reach the braze flow temperature at the same time as the joint. The induction heating solution must take into account the different thermal conductivities of the materials, and the time each material takes to get to the required temperature.

About Induction Heating

Induction heating is a fast, efficient, precise and repeatable non-contact method for heating metals or other electrically-conductive materials. The material may be a metal such as brass, aluminum, copper or steel or it can be a semiconductor such as silicon carbide, carbon or graphite. To heat non-conductive materials such as plastics or glass, induction is used to heat an electrically-conductive susceptor, typically graphite, which then transfers the heat to the non-conducting material.
