Abstract
This article uses ultrasonic guided wave to detect the processed pipeline. Determine location, size and the reason which causes echo through the echo A-scans. Use wavelet to analyze the raw data for the flat echo amplitude. This method helps to detect accurately the defect of the smaller echo amplitude.
