Improving the Method of the Calibration Multichannel Ultrasonic Flaw Detectors for Measurements with Angle Problems

Tomasz Ciszewski, Zbigniew Lukasik

Abstract

In the article an improved method of measurements synchronization which uses the cross correlation function and calibration patterns is presented. The previous version of the method turned out to be not precise enough if angle probes were used during the measurements. Complementing the existing procedures with additional resampling of the signal eliminated in practice the mentioned problems. The presented calibration strategy reduces the time of preparing multi-channel flow detector for the test, allows the correction of spatial placement of the probes and allows to improve the repeatability of the measurements. It also allows to use angle probes and it is suitable for different research methods (echo, shadow or tandem method).
