The two methods are presented for non-stationary leakage signals based on original feature gradate. One is a combination of the peak-peak and grads, the other is mean energy method, with the methods eliminate influence of noise and the stress concentration identification is improved. Based on the relativity for wavelet coefficient square, the signal singularity detection theory of wavelet transform was employed to determine metal magnetic memory. Experiment shows that the method is valid for leakage signal.
