Abstract

A system (10) for nondestructive evaluation of a test object (12) includes a platform (14), an electromagnetic acoustic transducer (EMAT) (16) to create acoustic vibrations (18) that travel along the test object (12); an infrared detector (20) positioned to record thermal images (200) of a plurality of test areas (24, 26, 28) on the test object (12) to detect flaws (30) in the test object (12) as the platform (14) and the test object (12) move relative to each other; and a control (22) connected to actuate the EMAT (16) and the infrared detector (20), synchronize the creation of vibrations (18) with the recording of thermal images (200), receive a signal from the infrared detector (20) indicative of the thermal image (200) of the surface (23) of the test object (12), and record locations of the flaws (30) appearing on the thermal images (200) of the test areas (24, 26, 28), all as the platform (14) and the test object (12) move relative to each other.
