In this paper the method of crack detection, localization and estimation of its relative depth using wavelet analysis was presented. Basing on obtained results, which were based on the analysis with application of B-spline wavelet the consequences of inappropriate selection of wavelet order for the analysis was shown. In the case when the values of wavelet order were too low the detail coefficients were biased by the inappropriately filtered signal, which cause a significant increase of detail coefficients values in the location of a crack, while when the values of a wavelet order were too high the decrease of values of detail coefficients were observed due to the power losses caused by increased together with the wavelet order the length of effective support of a wavelet.
