induction brazing of compressor copper fittings

A manufacturer of cooling systems would like to switch from torch brazing to induction brazing in order to improve cycle times and achieve repeatability.

Industry: Appliances & HVAC


The UBraze handheld induction brazing gun successfully replaces torches. It is safe and flexible solution which allows the operator to achieve the desired repeatability by focusing the heat to the desired area only. UBraze is paired with a 15 kW power supply which can be programmed according to any brazing requirements.


The client has provided copper and steel fittings of different shapes ranging between 1/8’’ up to about ½’’. A soldering vice is used to hold the assembly in position. Silver braze is used in this application to make the joint stronger and allow better flow. All parts were brazed at the power of 7.5 kW and 1500°F (815°C).


Induction brazing provides fast and efficient method to produce high-quality brazed joint.
