AUTOMATED ULTRASONIC INSPECTION OF ELONGATED COMPOSITE MEMBERS USING SINGLE-PASS ROBOTIC SYSTEM

摘要

Apparatus and methods for ultrasonic inspection of elongated composite members in a single scan pass using pulse echo phased arrays operating in a bubbler method. The system concept is fully automated by integrating an inspection probe assembly to a robot and using the robot to move the inspection probe assembly along the part (i.e., outside of an inspection tank); and by integrating tooling fixtures that move out of the way as the inspection probe assembly travels along the length of the part during the inspection. In addition, the system allows for generally elongated composite members having lengthwise variation in shape, curvature and dimensions.
