What is a common outcome of using the X-Ray NDI method?

Using the X-Ray NDI (Non-Destructive Inspection) method is primarily associated with identifying internal defects within materials, such as internal cracks. This technique employs X-ray radiation to create images of the interior structure of an object, enabling inspectors to detect flaws that are not visible on the surface.

When X-rays pass through an object, they will differentiate between areas of varying density, allowing for the visualization of cracks, voids, and inclusions that may compromise the integrity of the component. As a result, the main and most common outcome of using X-Ray NDI is indeed the identification of internal cracks, which is crucial for ensuring safety and reliability in aviation applications.

In contrast, while other listed outcomes such as increased physical strength of parts, surface shadowing, or temperature reduction may be relevant in different contexts, they do not specifically pertain to the primary function or common result of the X-Ray NDI method itself.
