Abstract
A method for nondestructive testing of the pipes for detecting surface flaws is disclosed. With of the method, flaws can be detected and analyzed in near-real-time while the pipe is produced. The data obtained by ultrasound sensors are digitized in a time window following a trigger pulse, and the digitized data are processed in a digital processor, for example a DSP, using wavelet transforms. The evaluated quantity is compared with a reference value, wherein a determined flaw-based signal can be uniquely associated with the flaw located on the pipe surface.
