Why induction brazing?
Induction brazing can produce strong, visually attractive, and shock-resistant joints compared to torch brazing. So, it overtakes conventional brazing due to the following potential benefits：
No open flame is involved in the induction brazing process. As in torch brazing, the flame is generated by fuel gases such as oxygen/acetylene or other gases. Explosion hazards are always associated with gas cylinders which must be handled carefully. No such hazard is involved in induction brazing.
Induction heating supplies more energy per mm2 than an open flame. Induction heating can braze more parts per hour than any other brazing method. In furnace brazing, the entire assembly is brought into the furnace, whereas in the case of induction brazing, the localized part is heated, and filler flows into the joint through capillary action.
- High rate of repeatability
Variables such as time, positioning, fixtures, alloys, and temperature are controllable. Enter the required parameters, and the system will repeat the heating cycle. For temperature control, the induction brazing equipment installs pyrometers, thermocouples, or visual temperature sensors.
No contact with the part is necessary during the process. It provides homogenous and minimal distortion.
The device occupies a small space on the factory floor.
In flame brazing, oxidation, scaling, or carbon deposits can build up on the part. To clean the part, flux (which can weaken the joint) or expensive chemical baths are traditionally used. Vacuum bath furnaces can overcome these issues but possess limitations such as large size, lack of quality control, and poor efficiency. Induction brazing solves these problems as no post-milling or grinding is required since the joint is so clean and tidy.
