What Is Induction Soldering?

Induction soldering is a process in which a precise electromagnetic field is used to heat two or more electrically conductive materials in order to join them with a filler material that melts at a temperature below the melting point of the joined materials.

induction soldering offers numerous benefits

What Benefits Does Induction Soldering Offer? 

  • Meets tight production tolerances with precise localized heat to small areas creating pinpoint accuracy

  • Soldering with induction increases production rates with faster heating cycles

  • Reduces defect rates with repeatable, reliable heat

  • Eliminates variability from operator-to-operator, shift-to-shift

  • Maintains metallurgical characteristics of the individual metals

Popular Induction soldering Application Notes

Select from our most requested soldering notes to learn how induction can improve the efficiency, effectiveness and safety of your heating process.


Soldering Co-axial Wire to a Metal FrameSoldering Co-axial Wire to a Metal Frame

Given the small size of the part and the assembly's geometry, a graphite cylinder was required as a susceptor.

Heating a Kovar Ferrule for Glass SolderingHeating a Kovar Ferrule for Glass Soldering

The solder formed a relatively uniform domed seal around the fiber despite the asymmetry of the open C coil. It took under 10 seconds to heat the part to soldering temperature

Soldering Four Fusible Copper StripsSoldering Four Fusible Copper Strips

Soldering with Induction takes under 10 seconds to heat four copper strips concurrently, resulting in a boost in throughput for the client. Induction is a highly repeatable process that heats just the area of the copper strip that requires it

Soldering a pair of magnetic steel pinsSoldering a pair of magnetic steel pins

Soldering with induction required under 10 seconds and is a highly repeatable process; the customer can expect the same result every time with only the portion of the part requiring heating being heated.

Soldering a rivet onto a steel tank cap with induction heatingSoldering a rivet onto a steel tank cap with induction heating

Soldering with induction proved faster than the client's previous heating torch process. It is also is a repeatable heating process, so the client gets superior results and is more energy efficient than torch heating.


Soldering Brass and Copper ComponentsSoldering Brass and Copper Components

A solder wire preform was placed on the part to allow for repeatable placement of solder in every joint. Four top or four bottom joints will be heated at one time within 2-3 minutes for the soldering application.

Heating a Copper Assembly for SolderingHeating a Copper Assembly for Soldering

To heat a glass feed-through inside a copper block for a soldering application, one side at a time. This was a new application/process for the client.

Soldering Ferrule and Module AssemblySoldering Ferrule and Module Assembly

To heat ferrule and module assemblies for a soldering application in the fiber optics industry.

Soldering copper tabs for stringing, tabbing solar panelsSoldering copper tabs for stringing, tabbing solar panels

Induction's precision soldering ensures repeatable results and less damage to surrounding substrates while demonstrating reduced heat loss and lower energy usage...

Soldering electrical wire to a copper groundingSoldering electrical wire to a copper grounding

For this grounding lug soldering application, induction delivers consistent result is achieved each time and does not present a flame, so it helps create a safer, cooler working environment than other methods

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.
