SCR induction brazing can be done in two ways: single shot and segment brazing. The major difference between the two methods is that the former needs more heating power. When the diameter of the SCR is less than 1200 mm, single shot brazing is used. EFD Induction’s series of Sinac universal power generators provide a wide range of heating power from 25 KW up to 200/320 KW. A temperature regulating system can be integrated into Sinac for closed loop control of the brazing power. Both the set and real time temperature curve can be displayed on the Sinac’s monitor and stored in the memory stick at the ECU. Also, Minac’s ECU can monitor, print and store the feedback temperature. Normally there are two ECU-controlled pyrometers in the system: one for measuring the temperature in the SCR and the other for measuring the temperature on the copper bar to ensure it reaches the brazing temperature.
EFD Induction can provide customized, turn-key solutions for virtually any SCR brazing task. These solutions include the equipment, optimized temperature curves, customized coils and a comprehensive range of training and service support.
