摘要：
The eddy current test method for determining weld defects is based on the interaction between the radiated electromagnetic energy in the frequency range from 100 Hz to 100 MHz and the metal to be tested. This paper describes the current status of this method and recent new developments intended for an increase of its information content by employing multiple frequencies.
