Abstract
Alternative magnetic leakage flux method was developed from the eddy current testing and traditional magnetic leakage flux testing, and it was advantageous for surface flaw recognition. The fast flaw-recognition model based on the magnetic field measurement and the depth-detection model based on the frequency sweeping method were built. Experimental results proved their accuracy.
