High Frequency Welding Machine

What is High Frequency Welding Machine

The high frequency welding machine is different from other welding machines, its function and use are not just a single welding. The high frequency welder can be used not only for welding various metal materials, but also for diathermy, melting, heat treatment and other processes. Welding is just one of its many uses.

There is a set of unique electronic circuits in the high frequency welding machine, which converts the low frequency alternating current (50Hz) input from the power grid into high-frequency alternating current (generally above 20000Hz). After the high frequency current is applied to the inductance coil (induction coil), it is converted into a high frequency magnetic field using the principle of electromagnetic induction and acts on metal objects in the magnetic field. The eddy current effect is used to generate an induced current in a metal object that is proportional to the strength of the magnetic field.

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 the eddy current flows in a metal object, heat is generated by the principle of electrothermal effect with the help of the inherent resistance value inside. This heat is generated directly inside the object. Therefore, the heating speed is fast and the efficiency is high. It can instantly melt any metal.The heating speed and temperature can be controlled. This induction heating equipment is especially suitable for heat treatment quenching, annealing, metal diathermic forging, extrusion forming, brazing, etc.

Application in Forging Industry

1. Heating and bending the steel plate.
2. Standard parts and heat-through forming of fasteners.
3. Heat penetration of hardware tools, such as pliers, wrenches, etc.
4. Cone shank extrusion of prospecting drill rod.
5. Steel pipe diathermy forming such as elbow.

High frequency welding machine has many advantages. It is high safety factor. No flammable and explosive gas is needed, which guarantees the safety of life and property. High frequency induction welding machine is energy conservation and environmental protection. During the welding process, no harmful gases such as carbon monoxide and carbon dioxide are produced. With electricity used, the cost is greatly reduced compared to the use of acetylene, gasoline, oxygen, LPG and other gases, saving at least tens of thousands of yuan a month. High frequency induction welding machine is high efficiency and low cost. Traditional brazing has low temperature, high thermal radiation, high cost and risk of explosion. The flame temperature of the plasma brazing machine can be adjusted, the welding temperature can reach more than 2000 degrees and the stability is high, which is more than twice the welding speed of acetylene. It is also sustainable welding for 12 hours.
