Development of a Novel Self-adaptive Contacting Ultrasonic Inspecting System for Welding Belt on Pipeline

摘要

For the requirement of online ultrasonic inspection for welding belt on pipeline, and the influence of its surface contour error (roundness) on stabilization of the clearance between the probe and the work pieces, a novel self-adaptive contacting ultrasonic scanner is advanced, which makes the ultrasonic wave transmit into the rotational part along with the normal direction of the detecting surface so as to realize online ultrasonic flaw-detection on pipelines. Based on those works, a software system is also developed, which realizes the requirement of online ultrasonic flaw detection process. The practical application proves the developed system can promote both the inspection quality and the efficiency of .welding belt on pipeline.
