Induction Brazing Machines

Delmer induction brazing systems provide controlled, localized heating for brazing copper, brass, steel and other compatible assemblies. Induction is particularly useful when a repeatable joint temperature, short heating cycle, clean work area and consistent production process are required.

Applications include copper tube brazing, HVAC and refrigeration assemblies, electrical connections, carbide tool brazing, automotive components and general industrial joining. The correct system is selected from the workpiece material, joint geometry, brazing alloy, target temperature, heating time, production rate and available electrical supply.

Where induction brazing is used

Copper tube and pipe: localized heating of tube-to-fitting joints and assemblies.
HVAC and refrigeration: repeatable brazing of copper and brass connections.
Electrical components: busbars, terminals, connectors and conductive assemblies.
Carbide tooling: brazing carbide tips, inserts and cutting-tool components.
Automotive and general engineering: joining shafts, rings, brackets and precision assemblies.

How Delmer sizes an induction brazing system

There is no single power or frequency that is correct for every brazing application. Delmer evaluates the material, joint mass, diameter or dimensions, brazing alloy, required temperature, heating zone, cycle time and production quantity. Coil or inductor geometry is then matched to the component so energy is concentrated where the joint needs to be heated.

Application factor	Why it matters
Base material	Electrical and magnetic properties influence heating behaviour.
Joint geometry	Determines coil shape, coupling and heating uniformity.
Brazing alloy	Sets the required process temperature and heating sequence.
Heating time	Determines required process power and production capability.
Production rate	Influences duty cycle, automation and cooling requirements.

Induction brazing machine configuration

A typical Delmer system can include an induction power unit, work coil or custom inductor, cooling system, operator controls, foot or start control, temperature or process monitoring and an optional automated handling arrangement. For machine builders, the induction generator can also be integrated into a larger production line.

Why use induction instead of open-flame heating?

Localized heat can reduce unnecessary heating of surrounding components.
Repeatable electrical control supports consistent production cycles.
No combustion flame is required at the heating point.
Coils can be engineered around specific joint geometries.
Automation and interlocks can be incorporated into production equipment.

Engineering Focus: Joint, Filler and Coil

For brazing, joint geometry and filler alloy determine where and how heat must be delivered. Coil clearance, coupling, heating time and component movement should be established from the actual assembly rather than copied from a generic machine specification.

Frequently Asked Questions

Can induction braze copper pipes?

Yes. Copper tube and fitting brazing is a common induction application when the joint geometry and heating cycle are suitable.

Can one induction brazing machine handle different components?

Yes, where the power range, frequency, coil design and process controls are suitable. Multiple interchangeable coils may be used for different workpieces.

Does Delmer supply the induction coil?

Coil or inductor design should be matched to the application. Provide component drawings or photographs and Delmer can assess the required heating arrangement.

What information should I send for an induction brazing quotation?

Send material, component dimensions, joint drawing or photograph, brazing alloy, target temperature, desired heating time, production quantity per hour and available electrical supply.

Request an induction brazing application assessment

For a technical quotation, provide the component drawing, material, joint dimensions, brazing alloy, target temperature, cycle time and production requirement. Delmer can then recommend a suitable induction heating configuration and coil concept.
