X-ray radioscopy using microfocus tubes
X-ray inspection with microfocus tubes uses a very small focal spot size to enable geometric magnification and precisely detect fine pores and cracks in castings.
Physical-Chemical Mechanism of Action
Microfocus tubes produce a very small focal spot size, making the X-rays more concentrated and thus stronger. This leads to higher resolution and precision in radiographic testing.
Metallurgical Relevance & Risks in Welding
This technique enables precise detection of fine pores, cracks, and other inclusions in castings. Missing or insufficient inspections can lead to safety risks, as unknown defects could compromise the material's structure.
Workshop Practice & Action Guidelines
Use microfocus tubes for radiographic testing of castings when high precision is required. Ensure the X-ray machine is properly calibrated and the test objects are adequately prepared. Carefully evaluate the images to detect all possible defects.
