How does the high-frequency induction heating welding machine work?

Also known as high-frequency heating machine, high-frequency induction heating equipment, high-frequency induction heating device, high-frequency heating power supply, high-frequency power supply, and high-frequency electric furnace. High-frequency welding machines, high-frequency induction heating machines, high-frequency induction heaters (welders), etc., as well as medium-frequency induction heating equipment, ultra-high frequency induction heating equipment, etc. The range of applications is very wide.

Working principle: First, a set of unique electronic circuits are used in the high-frequency machine to convert the low-frequency alternating current (50Hz) input from the power grid into high-frequency alternating current (generally above 20,000Hz); high-frequency current After being added to the inductor coil (i.e. induction coil), it is converted into a high-frequency magnetic field using the principle of electromagnetic induction, and acts on the metal object in the magnetic field; the eddy current effect is used to generate an induced current in the metal object that is proportional to the strength of the magnetic field. (That is, eddy current); (This eddy current is affected by the skin effect. The higher the frequency, the more concentrated it is on the surface of the metal object). When eddy current flows in a metal object, it will use the inherent resistance value inside to generate heat using the principle of current heating effect. This kind of heat does not rely on external heat transfer like other heating methods. It is generated directly inside the object. Therefore, this heating method is fast and efficient. If necessary, it can melt any metal object in an instant. Moreover, its heating speed and temperature are controllable.
