Induction Soldering

Soldering with induction can improve your soldering process without flame or irons. Soldering with induction heating focuses energy only in your part. Solder your materials in a repeatable, precise flameless process.

Soldering with induction heating is the process of joining metals by means of alloys that melt between 177 ºC - 371 ºC (350 ºF - 700 ºF). The strength of the joint depends on the chemical composition and cleanliness of the surfaces to be joined. Soldering produces liquid- and gas-tight joints quickly and at low cost. Most soldering applications are carried out in air, with the flux acting as a barrier to surface oxidation and interaction with the atmosphere. It is a convenient and economical way to produce joints when more complex joining machines are not available or cost effective.

Induction heating provides reliable, repeatable, non-contact and energy-efficient heat in a minimal amount of time. They are capable of heating very small areas within precise production tolerances, without disturbing individual metallurgical characteristics. Ambrell has offered cutting-edge induction soldering solutions since 1986.

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 steel, copper, aluminum, brass or it can be a semiconductor such as carbon, graphite or silicon carbide. 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.

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

Heating 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. There is no open flame with induction, which makes it a safer method of heating than torch heating.

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

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. Induction doesn’t have an open flame and introduces less heat into the work environment than a torch

Ambrell's induction heating equipment is very well suited for soldering applications in a production environment. Heat is applied to specific regions of a solder joint in a very controlled and precise manner. Induction soldering is well suited for production line applications (like fiber optic ferrule assemby) because of low time-to-temperature, high levels of repeatability and non-contact, clean heating.

Induction soldering machines output power ranges from 1 to 20 kW, depending on part and process requirements.

Ambrell Expertise:
  • Induction soldering equipment solves many of the application challenges.
  • Cleanliness of the solder joint surfaces is critical.
  • Both metal surfaces that are to be solder-joined must come to temperature at the same time.
  • If the temperature is too high, a strong joint cannot be created.
  • Instead of stick-feeding the solder, use a paste or preform solder that is placed in the joint areas before heating
