Which method uses X-rays to identify internal flaws in materials?

The method that uses X-rays to identify internal flaws in materials is X-Ray Testing, also known as Radiographic Testing. This technique involves passing X-rays through the material in question. When the X-rays penetrate the material, they are absorbed differently depending on the density and composition of the internal structure. Flaws such as cracks, voids, and inclusions will appear on the radiograph as areas of varying density, helping technicians assess the quality and integrity of the material.

X-ray testing is particularly advantageous for its ability to visualize hidden internal features without disassembling parts or structures. This non-destructive testing method allows for detailed examination, ensuring structural safety and reliability in various industries, including manufacturing, aerospace, and construction. The sensitivity and resolution of X-ray imaging make it an essential tool for quality control and assurance.
