A system for use in determining a location of a defect in an object is provided. The system includes an ultrasonic phased array configured to provide a sector scan of the object, a display, and a processor. The processor is programmed to provide a volume-corrected view of a sector of an ultrasonic inspection of the object on the display, wherein the object has a first surface defined by a first radius and a second surface defined by a second radius that is shorter than the first radius, receive gate parameters of a gate used to measure a location of a reflection of a beam emitted from the ultrasonic phased array, wherein the reflection is indicative of a defect on the first surface or the second surface, and calculate a location of the defect using the gate.

Phased array scanning into a curvature

The invention relates to a nondestructive ultrasonic test method in which at least one ultrasonic pulse is emitted into a workpiece under test by at least one ultrasonic transmitter (), the ultrasonic pulse is reflected on boundary surfaces within the workpiece, the reflected ultrasound is received by at least one ultrasonic receiver (), and the associated signals are evaluated, the ultrasound penetrating a damping block () that is arranged between the workpiece and the transmitter or receiver. The method is characterized in that it includes at least one step for determining at least one dimension (alpha, d, d) of the damping block () that is relevant for the ultrasonic test; in said step, the propagation time of at least one ultrasonic pulse which is generated by the ultrasonic transmitter (), is reflected on a boundary surface () of the damping block (), and is received by the ultrasonic receiver () is measured, and at least one dimension (alpha, d, d) of the damping block () that is relevant for the ultrasonic test is determined from the measurement.
