Handheld Induction Brazing Copper Tubing and Fitting Process

Objective

Induction brazing copper to copper: ½” copper tubing and copper fitting with brazing alloy and flux using the DWS-10 HandHeld Induction Brazing System.

Equipment

 DWS-10 handheld induction brazing heater

Materials

• Copper fitting

• Copper tubing

• Silver brazing alloy (pre-formed)

• Flux

Process:

1. The copper tubing and brass fitting were assembled together.


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


3. The assembly was placed within a fixture.


4. 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.


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


6. 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

induction brazing stainless steel to copper

Objective

Induction Brazing stainless steel to copper tubing. Objective is to evaluate induction brazing solution. Customer is looking to reduce defects and for a cleaner brazing environment.

Due to different pipe size and lower volume – evaluation is performed with a UBraze system.

Test1

Equipment

DW-HF-25kw induction brazing machine

Materials

Copper to Stainless steel tube

Power: 12.5kW

Temperature: 1400ºF to 1600ºF (760ºC to 871ºC)

Time: 9 to 11 seconds

Test2

Equipment

DW-HF-25kw induction brazing machine

Materials

Copper to Stainless steel

Power: 12.5kW

Temperature: 1400ºF to 1600ºF (760ºC to 871ºC)

Time: 9 to 11 seconds

Results and Conclusions:

Induction brazing test with U open coil was able to braze the parts in 9 to 11 seconds for the full braze cycle.

Operator training with this setup will be minimal.
