Abstract
A removable calibration assembly is disclosed which can be utilized to verify the angular mounting of transducers in an array employed in the inspection apparatus, to calibrate one axis of movement of the array with reference to a zero starting point or to measure and calibrate for the speed per unit of distance of the transducer's ultrasonic beam in the actual operating medium. The calibration assembly includes both a relatively infinitely large and a relatively infinitely small reflecting surface separated by known distances and a plurality of truncated cones, the tips of which are machined or adjusted to those angles at which certain of the transducers are to be mounted in the array. In addition, clamping means for securing the calibration assembly to the inspection apparatus at a predetermined orientation is provided.
