UltraFlex performing fast induction brazing for copper and steel fittings at 1500°F (815°C)
At power output of 7.5 kW, the target brazing temperature of 1500°F (815°C) had been reached, for each of the assemblies, within a fraction of the time needed when torch brazing is used.
In this demo application set up per request of a manufacturer of cooling systems, UltraFlex was required to braze copper and steel fittings of different shapes, with diameter ranging from 1/8'' up to about ½''. The assemblies were kept in place during the brazing process using a soldering vice, and silver braze was applied to the joints to make them stronger and enable better flow.
The UBraze handheld brazing gun along with a 15 kW power supply were considered the most appropriate equipment for this brazing application. UBraze is a mobile induction heating solution that can be used as a hand-held unit or can be integrated with a robotic arm for automated production lines. It is a durable assembly with an easy-hold grip, and a handle at the top of the unit to maximize stability. It is also a safe and flexible solution allowing the operator to focus the heat to a desired area only.
At power output of 7.5 kW, the target brazing temperature of 1500°F (815°C) had been reached, for each of the assemblies, within a fraction of the time needed when torch brazing is used. When used on the line, this induction brazing process would allow for faster cycle times, energy- and cost-efficiency and would ensure repeatability, with no dependency on the operator skills.
