Testing method for materials where an X-ray beam is directed at the material to detect internal defects. Beskrivning The process A radiographic generator [1] emits X-rays that hit and pass through the material [2]. The beams are then collected on an X-ray film [3] behind the material and any defects are detected by the various large amount of X-rays hitting the film depending on defect type, shape, and size. Radiographic Testing, RT Process films Advantages and disadvantages In comparison with alternative methods Can detect surface defects can detect internal defects can detect defects in the products covered by other products Minimal preparation required Highly directional Requires a lot of experience Health risks linked to radiation
