18KW High Frequency Induction Heating Machine


Rated Power Output:18KW

Frequency Range:100-200KHz


The high frequency induction heating technology utilizes the eddy current loss caused by the electromagnetic field on the surface of the workpiece to locally heat the workpiece, and can perform processing such as quenching and metal welding. With the continuous development of power electronics technology and the improvement of high-power switch tubes, high frequency induction heating machines have been rapidly developed.

Induction heating becomes an indispensable energy source for metallurgy, national defense, mechanical processing and other sectors such as casting, forging and shipbuilding, aircraft and automobile manufacturing.



1.The induction heating speed is fast,which solves the problem that the conventional heat treatment process causes the oxide layer to be too thick due to long heating time.

2.The heating position can be controlled freely, and does not generate excessive heat for the position where heating is not required, which satisfies the heat treatment requirements of special workpieces.

3.The operation is simple.There is no open flame, no high temperature, high voltage and it has good safety.

4.Small size, light weight, does not occupy too much production space,itcan move the working position at any time to facilitate production needs.

Working Principle of High Frequency  Induction Heating Machine

The working principle of induction heating is that a workpiece is placed in the inductor (coil), and when an alternating current of a certain frequency is applied to the inductor, an alternating magnetic field is generated around the workpiece. The electromagnetic induction of the alternating magnetic field produces a closed induced current in the workpiece – eddy currents. The high-density current of the surface of the workpiece is converted into heat energy, which raises the temperature of the surface layer, that is, achieves surface heating. The higher the current frequency, the greater the difference in current density between the surface layer and the inside of the workpiece, and the thinner the heating layer.

What is induction welding?

With induction welding the heat is electromagnetically induced in the workpiece. The speed and accuracy
of induction welding make it ideal for edge welding of tubes and pipes. In this process, pipes pass an induction coil at high speed. As they do so, their edges are heated then squeezed together to form a longitudinal weld seam. Induction welding is particularly suitable for high-volume production. Induction welders can also be fitted with contact heads, turning them into dual purpose welding systems.

What are the benefits?

Automated induction longitudinal welding is a reliable, high-throughput process. The low power consumption and high efficiency of DAWEI Induction welding systems reduce costs. Their controllability and repeatability minimize scrap. Our systems are also flexible—automatic load matching ensures full output power across a wide range of tube sizes. And their small footprints make them easy to integrate or retrofit into production lines.

Where is it used?

Induction welding is used in the tube and pipe industry for the longitudinal welding of stainless steel (magnetic and non-magnetic), aluminum, low-carbon and highstrength low-alloy (HSLA) steels and many other conductive
