Scanning X-Ray Detector For Nondestructive Testing

Abstract

For the nondestructive testing of long objects at the Paton Electric Welding Institute (Ukraine), an X-ray detector was created that uses a digital medical mini sensor. To increase the testing area, adjacent digital X-ray images are stored and stitched together by software into a combined image. The thickness of the objects that can be tested with this type of sensor, which has a maximal voltage of 70 kV, is 6 mm for aluminum. This imaging process can be used in a wide variety of applications. In a second approach, we developed a mobile detector with a remote control for radiographic testing (RT) of objects in limited and hard-to-reach spaces. One application utilizes a robotic car with independently controlled magnetic wheels that allows the detector to move in any direction over the entire surface of the object under test.
