Induction brazing using handheld brazing assembly

Equipment

UltraFlex UPT-W10

Ultraheat 10 kW Power Supply

HS-8 Heat Station

UltraFlex Handheld Brazing Assembly

Materials

• Copper Fitting

• Copper Tubing

• Silver Brazing Alloy (pre-formed)

• Flux

Frequency

52 kHz

Process:

The copper tubing and brass fitting were assembled together.

A pre-form of the silver brazing alloy was seated above the joint, and flux was added.

The assembly was placed within a fixture.

The C-Coil of the Brazing assembly was placed around the copper tubing and fitting, and the trigger was depressed. After roughly 40 seconds the brazing was complete.

The material was cooled in water following completion of the brazing.

The joint was then cross-sectioned to validate that the brazing process had produced a strong, high quality joint.

Results/Benefits:

Induction heating provides:

Strong durable joints

Selective and precise heat zone, resulting in less part distortion and joint stress than welding

Less oxidation

Faster heating cycles

More consistent results and suitability for large volume production, without the need for batch processing

Safer than flame brazing
