Which type of test utilizes X-rays to examine materials?

The use of X-rays to examine materials is specifically associated with the X-Ray Test, which employs X-ray radiation to penetrate materials and create images that reveal internal structures, flaws, or inconsistencies. This non-destructive testing method is particularly useful for identifying flaws in welds, castings, and other areas that may not be accessible through surface inspections.

In contrast, the Magnetic Particle Test is designed to detect surface and near-surface discontinuities in ferromagnetic materials using magnetic fields and ferrous particles. Visual Inspection relies on the human eye and is useful for identifying surface irregularities, while the Eddy Current Test involves the use of electromagnetic fields to detect surface and near-surface defects in conductive materials. While these methods are valuable for different applications, they do not utilize X-rays, which is the key characteristic that confirms the correctness of identifying the X-Ray Test as the appropriate choice.
