ABSTRACT:
An ultrasonic scan assembly is adapted to efficiently scan a surface and cross-section of a wall of an elongated cylindrical object. The ultrasonic scan assembly has a rotatable sensor section capable of rotating as the scan assembly is advanced axially along the elongated cylindrical object. In operation, the scan assembly is advanced in an axial direction along elongated cylindrical object, and the sensor section of the scan assembly is rotated so as to create a helical scan pattern. For at least a portion of the cylindrical object, the angular velocity of the sensor section is modulated. As a result, that portion of the cylindrical object is scanned at more than one scan rate.
