induction brazing brass pipe to brass part

Objective High Frequency Induction Brazing brass pipe to brass part and a brass tip in under one minute using induction.

Equipment DW-UHF-6KW-III handheld induction brazing machine 2 turns coil Materials • Wide brass part • Brass pipe • Silver-based brazing alloy, provided by customer

Test 1 – Pipe to wide part: Key Parameters Power: 4.4 kW Temperature: Approximately 1400° F (760° C) Time: 38 sec

Test 2 – Pipe to tip: Key Parameters Power: 4.4 kW Temperature: Approximately 1400° F (760° C) Time: 17 sec

Process: Test 1

• The wide part and brass pipe are assembled and a brazing alloy ring is placed between them.
• The assembly is put inside the induction heating coil and induction heat is applied.
• The joint is completed in 38 seconds.

Test 2

• The tip and pipe are assembled and a brazing alloy ring is placed between them.
• The assembly is put inside the coil and induction heat is applied.
• The joint is completed in 17 seconds.

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 process than flame brazing
