Abstract

In this work, Phased array ultrasonic testing (PAUT) is calibrated for sound velocity, wedge delay, sensitivity and time corrected gain using side drilled holes and notches as reflectors.   The responses of the reflectors for various angles (40 – 70o) are studied and standardised.  The significant use of these reflectors and the cause of non-uniformity in notches, are analysed by comparing the reflection property of side drilled holes and surface notches for useful range of sectorial beam sets. Results are validated with the simulation studies.
