Product Profile

Impeder Cores for High Frequency Welding

 Ferrites Impeder Cores PP


  • Impeder cores are an essential accessory for welding tubes and pipes using high frequency waveguide heating. They concentrate the magnetic flux generated by the work coil into the area of the pipe joint. Consequently, using impeder cores greatly increases the efficiency of the welding process.
  • The new product profile covers a wide range of core types and sizes as well as the new IPH2 impeder material. The advantages of IPH2 are lower reluctance, lower losses at the application temperature and a wider frequency range compared with IPH.
