High Frequency Brazing Stainless Steel Fittings

Objective High Frequency Brazing stainless steel fittings to corogated (SS) hoses. The hoses are with sizes ID 1.575in (40mm) and ID 2.99in (76 mm).  The customer has never used induction heating before and is not familiar with the induction process. The goal of this test is to prove the strength of the joints. Equipment DW-UHF-10KW induction brazing machine Materials • Flexible metal hose • Ag45Sn brazing alloy

Test 1 Key Parameters Flexible metal hose with ID 1.575in (40mm) Equipment: DW-UHF-10KW induction brazing heater, custom coil – ID 1.654in (42mm), 1 turn Temperature: approximately 1382°F (750°C) Power: Pre-curie – 7kW Time: 28seconds

Test 2 Key Parameters Flexible metal hose with ID 2.913in (74mm) Equipment: DW-UHF-10kw induction brazing heater, custom coil – ID 2.992in (76mm), 1 turn Temperature: approximately 1382°F (750°C) Power: Pre-curie – 8 kW Time: 1 minute 20 seconds

Process:

1. Hose and fittings are prepared with borax flux paste in the surface area.
2. Brazing rod is prepared in form of a ring fitting around the diameter of the joint.
3. The hose and the fittings are placed into the coil.
4. Induction heating is applied to the area until the braze is completed.

Results/Benefits:

1. Power supply DW-UHF-10KW induction brazing machine meets the requirements for this process.
2. For better performance for bigger diameter joints, we recommend power supply DW-UHF-10KW  induction brazing heater.A special custom coil can be designed as well.
3. For the tests, static induction was used (see video), but flexible leads and coil or our DW-UHF series are also recommended.

Induction heating provides:

• Strong durable joints
• Selective and precise heat zone, resulting in less part distortion and joint stress
• 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 Tubing Joints

The Professional Induction Brazing Stainless Steel Tubing Joints Technology

The goal of this induction brazing application test is for Induction Brazing Stainless Steel Tubing Joints evenly for increased repeatability. Industry: Automotive Equipment:  DW-UHF-10KW induction brazing machine Time: 15 sec. Materials: Stay Silv Black Flux Temperature:  1472°F  (800°C) Power: 8 kW

Process: The two stainless tubes where joined together and an alloy ring was placed around the joint. Black flux was then applied to the joint for a better induction brazing process. The work piece was placed inside the helical coil for 15 seconds where 8 kW of induction heating power was applied. The work piece reached 1472°F  (800°C) and was successfully brazed.  The HLQ induction heating equipment recommend for this application is the  DW-UHF-10KW induction brazing heater along with a 10 kW power supply.
