Brazing Aluminum Tubing to Aluminum Parts

Objective

The objective of the application test is induction brazing aluminum tubing to aluminum parts in less than 15 seconds. We have aluminum tubing and an aluminum “receiver”. The brazing alloy is an alloy ring, and has a flow temperature of 1030°F (554°C).

Equipment

DW-HF-15kw induction heating machine

Induction heating coil

Materials

• Aluminum tube: 0.167” (4.242mm) OD, 0.108” (2.743mm) ID

• Aluminum component: ID .1675” (4.255mm), depth .288” (7.315mm),

chamfer at top area is 0.2375” (6.033mm) ID max

• Braze alloy in the form of two-turn alloy ring

• Flux

Key Parameters

Temperature: 1030°F (554°C)

Power: 5 kW

Time: 14 seconds

Process:

1. The Aluminum component and tube were assembled together with the alloy ring. Flux was added.


2. The part was positioned in the induction coil.


3. Several tests were conducted with different cycle times to confirm the heating time for a good braze.


4. At 15 seconds the assembly melted.


5. At 14 seconds, we had success for brazing aluminum to aluminum, and a good quality braze joint was achieved.

Results/Benefits:



The 5 kW induction heating system requested by the customer, will meet the customer’s time requirements for induction brazing.

• Precise control of the time and temperature


• Power on demand with rapid heat cycles


• Repeatable process, not operator dependent


• Safe induction heating with no open flames


• Energy efficient heating

Induction brazing aluminum pipes

Objective

High frequency induction brazing aluminum pipes

Equipment

DW-UHF-6kw-III handheld induction brazing machine

Materials

Аluminum to aluminum tube

Flared at interface 0.25” (6.35mm)

Brazed to steel tube 0.19” OD (4.82mm)

Power: 4 kW

Temperature: 1600°F (871°C)

Time: 5 sec

Results and Conclusions:

Induction heating provides:

• Strong durable joints


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


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


• Safer than flame brazing
