An ultrasonic testing assembly structured to examine a test object, wherein the test object has a surface, and the examination examines the structure of the test object under the surface as well as the profile of the surface. The ultrasonic testing assembly includes a sled assembly structured to support a plurality of ultrasonic transducers, the sled assembly including at least one support member having a lower surface, at least one surface ultrasonic transducer coupled to the sled assembly and structured to extend below the support member lower surface and further structured to engage the test object surface, the surface ultrasonic transducer structured to examine internal structure of the test object and provide a first output, at least one profiling device coupled to the sled assembly, the profiling device structured to measure the profile of the test object surface and provide a second output, and a control device structured to correlate the first output and the second output and to calculate a corrected output.

Device and method for ultrasonic inspection using profilometry data

An end effector for supporting an ultrasonic testing probe on a robot arm having a robot mounting bracket for use in a nuclear reactor pressure vessel. The end effector has a wrist assembly with a rotatable wrist axle. The wrist assembly is coupled to the robot mounting bracket and a probe assembly is coupled to the wrist shaft. The ultrasonic testing probe is floatably disposed within the probe assembly.

Floating ultrasonic testing end effector for a robotic arm

The present invention is a transport system for an inspection system that includes a flexible controller end effector for carrying inspection and gripping devices. The transport system includes a hollow flexible conduit through which control cables for the effector can pass unobstructed. A rotatable deflector assembly helps guide the end effector as it enters the steam generator using a rotatable deflector channel and an extension. A drive assembly provides axial movement control for the end effector allowing easy insertion and retrieval. The axial movement is provided by friction rollers coupled to an axial drive mechanism and mounted in a drive box. The drive assembly also provides orientation control to allow the end effector to be rotated by rotating the drive box which rotates the conduit held in place by the direction rollers. The drive assembly further provides two spatially fixed locations from which the axial and rotational motions can be provided. The flexible conduit is taken up from and gathered by a conduit basket outside the steam generator. The conduit basket includes a control assembly for controlling the end effector via the control cables passing through the hollow conduit.
