Based on the principle of electromagnetic induction, the workpiece rapidly generates Joule heat in a high-frequency magnetic field, enabling localized precise heating and brazing. It features extremely fast heating speed (response times on the order of seconds) and a small heat-affected zone, which can effectively preserve the properties of the base material. Currently, it is widely used in fields such as electronic components, hardware fittings, and automotive parts, offering tailored brazing solutions for a wide range of precision joining needs.
