Device for radiography without the use of film

摘要

A radiographic device for testing the welds of elongate, welded hollow bodies of metal without the use of film includes a liquid-cooled X-ray tube movable axially within the hollow body being tested and an X-ray image converter situated in the region irradiated by the X-ray tube. A high-voltage generator is fastened to a displaceable holder carriage for movement in directions parallel or vertical to the longitudinal axis of the hollow body being tested. At least one high-voltage cable is connected, via guide rollers arranged outside the hollow body being tested. The length of the cable is dimensioned to enable a displacement of the X-ray tube from one end to the other for the longest hollow body to be tested. Concrete shielding need only be slightly longer than the longest hollow body to be tested.
