Abstract

In this study, Ultrasonic Guided Waves have been generated by means of a system developed for producing the desired signal needed for excitation of guided waves and a Piezoelectric Sensor. After propagating, waves are measured using an ultrasonic probe and recorded via a digital oscilloscope. Subsequently, the received signals have been processed and filtered for de-noising in order to be compared. As investigating the parameters influencing the inspection ability of these waves, the receiving probe has been moved along the pipe and by changing number of input signal pulses and sweeping the frequency; signals have been recorded at the frequency in which amplitude is maximum. By sweeping the frequency in the range of 30 to 40 kHz, it is possible to receive an appropriate signal in each point of the test piece.
