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.

Induction Brazing Copper to Stainless Steel Process

High Frequency Induction Brazing Copper to Stainless Steel Process Technology

Objective

The objective of this induction brazing copper to stainless steel using a DW-UHF-40kw induction heating power supply with a custom heating station

Equipment

DW-UHF-40KW Induction Heating Power Supply

HLQ custom coil

Key Parameters

Power: 23.65 kW

Temperature: Approximately 1300°F (704)°C

Time: 3.5 mins

Materials

Cooper

4.5″ OD

0.5″ Wall Thickness

Stainless Steel  4″ OD

Braze Joint 2″

Process:

In order to start the induction brazing of copper to stainless steel the part was centered on a turntable. The induction brazing coil was then positioned around the copper because it is less efficiently heated than stainless steel. As the part was rotating, approximately 25kW were being applied to the coil. Once the brazed joint was close to the ideal brazing temperature, the alloy was hand fed onto the joint. The induction brazing of cooper to stainless steel was completed and successful.

Results/Benefits:

The result of the induction brazing copper to stainless steel application testing was a positive one, the induction brazing was completed and the copper to stainless steel was done seamlessly. This test resulted in high quality and repeatability of the brazed joints, increased productivity and control of the time and temperature.

Induction Brazing copper to copper pipes

High Frequency Induction Brazing copper to copper pipes Process

Objective: Induction Brazing copper to copper pipes

Equipment: DW-UHF-6KW-III handheld induction brazing heater

Materials:  Six Copper pipes (9.5 mm)

Power: 6 kW

Temperature: 1475 °F/ 800°C

Time: 20 seconds

Process:

The DW-UHF-6KW-III handheld induction brazing system with robot can automatically induction braze multiple joints located in predefined positions. For this brazing application a wire feeder was mounted to the DW-UHF-6KW-III induction brazing heater, which feds the alloy onto the copper joints. A nitrogen nozzle was also added to reduce oxidization of the joints, this helps minimize the brazed joints cleaning procedure. The robotic system is programmed to move to each joint and apply power for a pre-programmed amount of time. This ensures a repeatable and reliable brazing process. The induction brazing of copper to copper was performed successfully within 20 seconds per joint at 1475 °F.

The DW-UHF-6KW-III handheld induction brazing heater is ideal for flameless brazing of refrigerator compressors, heat exchangers, home appliance components and complex HVAC assemblies.
