An impeder core is an essential accessory for the welding of tubesand pipes using high frequency waveguide heating. The characteristics and durability of the impeder care have a significant effect on the efficiency and stability of the welding process. Thanks to advantages in technology and experience gained from manufacturing.

The impeder core concentrates the magnetic flux generated by the work coil into the area of the coil joint. Consequently, use of an impeder core massively increases the efficiency of the welding process.

For these applications, special ferrite materials are offered. They are having following excellent physical properties:

High curie temperature and a low temperature dependence of the initial permeability and of magnetic flux density in the working temperature range.
A high saturation flux density in the working temperature range upto 150°C
Low losses with increase of temperature.
A relative high amplitude permeability.
A high stability of the initial permeability vs. frequency upto I MHz.
Cores are available in 4 shapes, depending on the application
