Induction brazing is a welding method that uses high-frequency, medium frequency, or power frequency induced current as a heat source. High frequency heating is suitable for welding thin-walled pipe fittings. The use of coaxial cables and split type induction coils can be brazed on site away from the power source, especially suitable for welding large components such as pipeline joints that need to be disassembled on rockets. It is also commonly used in the electronics industry for pin soldering, which is used to heat the solder joints in the area simultaneously, and to complete the soldering by sending the tin wire to the solder joints through a tin feeding mechanism.

During induction brazing, the brazing part of the component is placed in an alternating magnetic field, and the heating of this part of the base material is achieved through the resistance heat generated by the induced current in the alternating magnetic field. The higher the frequency, the smaller the depth of current penetration. Although the surface layer is rapidly heated, the thickness of the heating is thinner. The interior of the part can only be heated by the heat conduction from the surface layer to the interior, which is called the skin effect. Induction coil is an important component of induction brazing equipment. The basic principle for designing and selecting induction coils correctly is to ensure rapid, uniform, and efficient heating during welding. Usually, induction coils are made of pure copper tubes, which are cooled by water during operation. The thickness of the tube wall should be less than the depth of current penetration, generally 1-1.5mm. Therefore, it can be seen that using excessively high AC frequencies is not advantageous, and a frequency of around 500kHz is generally more suitable. In addition, the skin effect is also related to the material's resistivity and permeability. The larger the resistivity, the smaller the permeability, and the weaker the skin effect. Conversely, the skin effect becomes more significant.
