Working Principle of Induction Brazing Machine
Induction Coil
The Induction Brazing Machine consists of an induction coil, also known as the work coil, which is typically made of copper tubing or flat copper conductors. The coil is custom-designed to fit the shape and size of the workpieces to ensure efficient energy transfer and uniform heating. When an alternating current (AC) is passed through the coil, it generates a rapidly changing magnetic field.
Electromagnetic Induction
When the AC current flows through the induction coil, the rapidly changing magnetic field induces eddy currents in the workpieces. These eddy currents, also known as Foucault currents, flow in a circular pattern within the conductive materials. According to Lenz's law, the direction of the induced currents opposes the change in the magnetic field that induces them.
Heat Generation
The eddy currents flowing through the conductive workpieces result in resistive heating due to the electrical resistance of the material. This resistive heating effect is responsible for generating heat in the workpieces. The heat is concentrated near the surface of the material, allowing for localized heating without significantly affecting the surrounding areas.
Filler Metal Application
Before the brazing process begins, a filler metal, usually in the form of a preformed brazing alloy or paste, is applied to the joint area between the workpieces. The brazing alloy has a lower melting temperature than the base metal, allowing it to melt and flow into the joint during the heating process.
Heating and Brazing
As the induction coil generates heat in the workpieces, the temperature rises rapidly. The heat causes the brazing alloy to melt, forming a liquid phase that wets the surface of the workpieces. The molten alloy flows into the joint due to capillary action, filling any gaps and forming a metallurgical bond as it solidifies.
Key Components of Induction Brazing Machine
Induction Brazing Machine tools consist of several key components that work together to achieve efficient brazing:
