Original Abstract

The new method of non-destructive testing field is presented in this paper. This method consists of two signals. The electric ac signal with frequency fE and the ultrasonic signal with frequency fU. The ultrasonic signal changes resistance of the measured sample by frequency of ultrasonic excitation fU. Defects in the material are causer larger changes resistance then in the material without defects for the same amplitude of ultrasonic signal
