Abstract
A spherical body inspection apparatus including a support arrangement realized to support a spherical body during an inspection procedure; a probe arrangement comprising a plurality of ultrasonic testing probes arranged about the spherical body such that the ultrasonic testing probes target a common test point at the surface of the spherical body; and a displacer for effecting at least one relative rotational displacement between the spherical body and the probe arrangement. Also described is a method of inspecting a spherical body.

A spherical body inspection apparatus comprising:
- a support arrangement realized to support a spherical body during an inspection procedure;
- a probe arrangement comprising a plurality of ultrasonic testing probes arranged about the spherical body such that the ultrasonic testing probes simultaneously target a common test point at the surface of the spherical body and at least one of the plurality of ultrasonic testing probes is arranged to emit an ultrasonic pulse that enters and exits the spherical body at the common test point and passes as a longitudinal wave through the spherical body and at least one other of the plurality of ultrasonic testing probes is arranged to emit an ultrasonic pulse that, after refraction into the spherical body, passes as a transverse wave along a chord of the spherical body to the common test point;
- and
- a displacer for effecting at least one relative rotational displacement between the spherical body and the probe arrangement.
A method of inspecting a spherical body, which method comprises:
- arranging a probe arrangement comprising a plurality of ultrasonic testing probes relative to the spherical body such that the ultrasonic testing probes simultaneously target a common test point at the surface of the spherical body with at least one ultrasonic pulse that enters and exits the spherical body at the common test point and passes as a longitudinal wave through the spherical body and at least one ultrasonic pulse that, after refraction into the spherical body, passes as a transverse wave through the spherical body along a chord to the common test point;
- and
- actuating the ultrasonic testing probes to emit the ultrasonic pulses while
- effecting at least one relative rotational displacement between the spherical body and the probe arrangement of the ultrasonic testing probes.
