Description

Technical Field

[0001] The utility model relates to a high frequency welding machine, in particular to a novel high frequency welding machine. Background Art

[0002] High-frequency welding machines can not only be used for welding various metal materials, but also for processes such as heat penetration, smelting, and heat treatment. Welding is just one of its many uses. The working principle is: first, a set of unique electronic circuits in the high-frequency machine converts the low-frequency alternating current (50Hz) input from the power grid into high-frequency alternating current (generally above 20,000Hz). After the high-frequency current is added to the inductor (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; using the eddy current effect, an induced current proportional to the magnetic field strength is generated in the welded part. This eddy current is affected by the skin effect. The higher the frequency, the more concentrated it is on the surface of the welded part, and any metal object can be melted instantly. Among them, the induction coil, as the main heat-generating component of the high-frequency welding machine, is connected to the positive and negative poles of the high-frequency power supply. The induction coil generates a magnetic field through the induced current. The current induction coil is directly fixed on the welding machine body, and the disassembly of the induction coil is complicated, resulting in the high-frequency welding machine being suitable for welding parts of basically the same size, and cannot be used for welding parts of more different sizes and specifications; in addition, the magnetic field generated by the induction coil affects the rapid vibration of the molecules of the welding part, generating a large amount of heat and reducing the magnetic field strength.
