X-Ray Microtomography
X-ray microtomography images microscopic defects and pore structures in the micrometer range with high resolution.
Physical-Chemical Mechanism of Action
X-ray microtomography uses high-energy X-rays that pass through the material and are recorded by a detector. Density differences in the material cause different levels of absorption, resulting in a three-dimensional image.
Metallurgical Relevance & Risks in Welding
This technique allows detailed analysis of internal structures of weld zones and workpieces. It helps detect pores, cracks, deformations, and other defects not visible with optical methods. Misinterpretation or inaccurate measurements can lead to missed diagnoses, posing risks to the safety and service life of components.
Workshop Practice & Action Guidelines
Use X-ray microtomography for precise analysis of weld zones after welding. Make sure the material is dry and free of surface contaminants. The measurement should be performed in a controlled environment to minimize factors like humidity or temperature. Carefully interpret and document the results.
