Why choose Induction Brazing?

Why choose Induction Brazing?

Induction heating technology is steadily displacing open flames and ovens as the preferred heat source in brazing. Seven key reasons explain this growing popularity:

1. Speedier solution
Induction heating transfers more energy per square millimeter than an open flame. Put simply, induction can braze more parts per hour than alternative processes.
2. Quicker throughput
Induction is ideal for in-line integration. Batches of parts no longer have to be taken aside or sent out for brazing. Electronic controls and customized coils let us integrate the brazing process into seamless production processes.
3. Consistent performance
Induction heating is controllable and repeatable. Enter your desired process parameters into the induction equipment, and it will repeat heating cycles with only negligible deviations.

4. Unique controllability

Induction lets operators view the brazing process, something that is difficult with flames. This and precise heating minimize the risk of overheating, which causes weak joints.
5. More productive environment
Open flames create uncomfortable working environments. Operator morale and productivity suffer as a result. Induction is silent. And there is virtually no increase in ambient temperature.
6. Put your space to work
DAWEI Induction brazing equipment has a small footprint. Induction stations slot easily into production cells and existing layouts. And our compact, mobile systems let you work on hard-to-access parts.
7. No-contact process
Induction produces heat within the base metals — and nowhere else. It’s a no-contact process; the base metals never come into contact with flames. This protects the base metals from warping, which in turn increases yield and product quality.

Brazing Cutting Tool with Induction

Brazing Cutting Tools with Induction

Objective: To braze cone and shaft for a cutting tool

Material Customer supplied parts

Temperature indicating paint Braze preforms

Temperature 1300 – 1400 ºF (704 – 760 °C)

Frequency 400 kHz

Equipment: DW-UHF-6kw-I, 250-600 kHz induction heating system, including remote heat station using two 0.66 μF capacitors (total 1.32 μF) A two-position, two-turn induction heating coil designed and developed specifically for this application.

Process: Two sets of parts are placed in the individual coils. Braze preforms are placed on the cone at the joint. The assembled part is placed inside the induction heating coil and heated until the braze melts.

Results/Benefits: efficient coil design enables simultaneous heating of two parts on the single 2kW system. dual braze is accomplished within required process time, increasing process throughput
