Abstract:

An ultrasonic inspection system for inspecting areas of tubular members and providing a display of any internal flaws therein. In order to operate in a confined work space a probe containing ultrasonic transducers is provided together with a rotational and axial drive scanner which is linked to a remotely controlled manipulator. The scanner uses a wand supporting the probe at the upper end thereof. The manipulator locates the probe and scanner in alignment with the tube to be inspected. A stepping motor on the scanner drives the wand and the probe axially to a location just above the area to be inspected. A second stepping motor rotates the wand to enable the probe to perform a circumferential scan. The axial stepping motor then indexes the wand towards the lower edge of the area and another circumferential scan occurs. The indexing and circumferential scanning proceeds until the entire area is scanned.
