Induction brazing system is an advanced welding technology that uses high-frequency or medium frequency induction heating to heat the filler metal (brazing material) to a molten state and fill it into the joint between two or more workpieces. Through capillary action, the liquid brazing material wets the base material and solidifies to form a strong connection. This welding method has been widely used in many industries due to its fast, precise, and reliable characteristics.
working principle
The core of induction brazing system lies in induction heating technology, which generates an alternating magnetic field in the induction coil through alternating current. This magnetic field acts on the metal workpiece placed inside, causing eddy currents to be generated inside. The heat generated by eddy currents is sufficient to heat the brazing material above its melting point, but below the melting point of the base metal, thus achieving the goal of welding at a lower temperature.
component
Induction heating source: High frequency or medium frequency generator provides power.
Induction coil: used to generate a magnetic field.
Control system: Adjust heating power and frequency.
Clamping device: Fix the workpiece to ensure accurate positioning of the welding area.
