Durable and precise connections to ensure the efficiency of filtration systems.
Debris filters are essential components for removing impurities and particles in hydraulic and heating systems. Induction brazing is an ideal solution for achieving airtight and durable joints, preserving the structural integrity of the filter while ensuring optimal performance over time.
The adoption of induction brazing has resulted in strong and reliable joints, optimizing mass production while ensuring identical parts, thus reducing waste and rework.
This application involves the brazing of debris filters using medium-frequency induction technology to achieve excellent results. The ability to automate the entire production cycle further enhances the efficiency and quality of the finished products.
Details of the brazing process:
The thermal mass of the component ensured that the brazing alloy continued to……
The brazing program involves reaching a temperature of approximately 800° C and maintaining it for 5 seconds, the optimal time to allow the alloy to penetrate by capillarity and create the correct meniscus.
After the first brazing the main body is already hot, so the solution of using a power-temperature program is optimal to avoid cold or non-compliant brazings.
It is noted that the induction brazing time tends to stay constant after the first cycle as the temperature of the piece is already stabilized, which is why the quality of the brazing is perfect.
The Platinum MF25 generator (25 kW calibrated at 66% of power) was used for this application, the Ø10mm copper tubes were coupled with the respective copper tube base. We reconstructed a repetitive industrial process, brazing the tubes in sequence without resting the piece. Below we list the results:
The brazing is almost perfect. The times, after brazing the first tube, are significantly reduced since the “support” piece is already at temperature from the previous operations. Inductors made specifically for these tests are suitable for this type of brazing. However, they can still be optimized to specific geometries and the brazes can be further improved.
The customer is our focus: it is the commitment to excellence that we carry forward at Seit Elettronica.
In our company we have always considered customers at the center of our development and sales processes. We are convinced, in fact, that only a methodical approach that brings out critical issues and needs within production processes generates added value and successful investments.
