MICROCOMPUTER AIDED EDDY CURRENT INSTRUMENT FOR DETECTING THE CRACKS IN ELECTRODES BY MEANS OF TRANSMITTING-RECEIVING TECHNIQUE |
| |
| Abstract: | The principle of eddy current transmitting receiving technique for detecting the cracks in electrodes and the composition of the microcomputer aided instrument were described. The flaw waveform could be distinguished from those of fringing and lift off showed by means of the hardware and software designed. Accurate detection was realized by the instrument. |
