Method of scanning speed adjustment for ultrasonic flaw detector

Abstract

Abstract: In the ultrasonic flaw detection of small diameter tube weld, the new method for division of horizontal scale graduation and scanning speed adjustment of apparatus was proposed. By using of the leaning probe with large refraction angle, according to the primary wave of reflection pulse which was passed through the two test horizontal through hole in DL-1 test block in certain proportion, the scanning speed can be adjusted accurately. The method will have a great effect for accurate defect allocation and determining the properties of defect in the root of weld.

Key words: ultrasonic flaw detection, measurement, scanning speed, horizontal scale, incline probe
