Summary. Hello <>

The highest point of heating during high-frequency welding is located in the center of the induction coil. High-frequency welding is a welding method that uses the principle of electromagnetic induction for heating. In the high-frequency welding process, the induction coil generates a strong magnetic field through alternating current, and when the welded material enters the magnetic field, heat will be generated due to the resistance of the material to achieve the effect of heating.

Where is the highest point of heating in the induction coil during high-frequency welding.

Hello <>

The highest point of heating during high-frequency welding is located in the center of the induction coil. High-frequency welding is a welding method that uses the principle of electromagnetic induction for heating. In the process of high-frequency welding, the hail sensing coil generates a strong magnetic field through the AC source bridge electricity, and when the positive or welded material enters the magnetic field, heat will be generated due to the resistance of the material to achieve the effect of heating.

Induction coils are usually arranged around the weld area in a circular or spiral pattern. When the alternating current passes through the induction coil, the magnetic field will concentrate inside the circle, and the center of the circle will have the highest magnetic strength. As a result, the magnetic field is the most affected by the magnetic field and the temperature is the highest in the central position of the induction coil of the welded fluid material.

The correct use and operation method of IGBT high-frequency induction heating equipment to avoid human error and unnecessary trouble caused by self-production. First of all, we had to start it in strict order.

Metal heating (forging surface treatment) is possible

The English physicist Faraday's law of electromagnetic induction tells us that magnetism can generate electricity, and the Danish natural philosopher Oster's right-hand law (Ampère's law) tells us that electricity can generate magnetism. However, whether it is magneto-electrically or electromagnetically, the object to which it is directed must have good electrically conductive, magnetically conductive, or both electrically and magnetically conductive properties. Since only metallic materials are usually eligible, only a very small number of non-metallic materials, such as graphite, are eligible.

Therefore, electromagnetic induction heating technology is mainly used in the heating of metal materials and graphite.

So, how is heat generated? The alternating current output by the device is converted into a transmutable magnetic field through an inductance coil (inductive coil) and applied to a metal workpiece (or graphite) in the electromagnetic field. In this case, a large number of closed rotational currents (eddy currents) are naturally generated in the workpiece, and the currents are extremely large (equivalent to short-circuit currents) and a lot of heat is generated due to the thermal effect of the current (q i i r*t).

In addition, there is a hysteresis loss inside the workpiece, which also causes a certain amount of heat to be generated inside the workpiece (although this heat is usually only generated in ferromagnetic objects containing magnetic molecules). As a result, the workpiece heats up dramatically in a very short period of time (often seconds) and, if required, any metal material can reach its melting point and graphite can reach sublimation.

According to the frequency of the alternating current output by the equipment, the induction heating technology can be divided into five categories according to the working frequency: low-frequency induction heating, medium-frequency induction heating, ultra-audio induction heating, high-frequency induction heating and ultra-high frequency induction heating.

If it burns red, add a little pressure, and it will be together.

Stainless steel also conducts some magnetism, and copper can be inductively heated.

6. The sensor is placed inside the workpiece, with a remote control switch or a manual heating button to start the right. When you meet the requirements, disconnect the remote control switch or panel to turn off the heating.

7. When the work is completed, stop the heating operation, turn off the "control switch" on the host panel, and then turn off the air conditioner power distribution switch.

2. Heating (hot forging, hot fitting, melting).

Hot forging is mainly to heat the Duanye workpiece to a certain extent (depending on the material, the temperature is also different) through punching, forging or other forms to press him into other shapes.

Thermal fit mainly refers to the heating of metals between different metals or between metals and non-metals, and the use of the principle of thermal expansion or thermal melting to link together.

Smelting refers to the high temperature of the metal to be melted into a liquid.

3. Heat treatment (surface quenching).

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, 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 of all, a set of unique electronic circuits in the high-frequency machine will convert 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 added to the inductance coil (i.e., the induction coil), it is converted into a high-frequency magnetic field by 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 (i.e., eddy current) in a metal object that is proportional to the strength of the magnetic field; (This eddy current is affected by the skin effect, and the higher the frequency, the more concentrated it is on the surface of the metal object). When eddy currents flow through a metal object, heat is generated using the principle of the thermal effect of electric currents with the help of the resistance value inherent in the metal.

This heat is not transferred from the outside as in other heating methods. It is generated directly inside the object. Therefore, this heating method is fast and efficient.

If desired, it can melt any metal object in an instant. Moreover, its heating rate and temperature are controllable.

The main uses of high-frequency induction heating machine are: metal heat treatment, metal quenching, metal annealing, metal tempering, metal diathermy, metal brazing, silver welding, brazing, metal heat molding, metal melting, metal implantation plastics, etc.
