What is one primary goal of non-destructive testing (NDT)?

One primary goal of non-destructive testing (NDT) is to prevent damage while assessing materials. NDT is designed to evaluate the properties of a material, component, or system without causing any harm to it. This is crucial in various industries because it allows for the identification of defects, stresses, and other issues that might compromise the integrity of a material or structure, all while preserving its usability. By enabling ongoing inspection and maintenance, NDT helps enhance the safety and reliability of structures and components, reducing the likelihood of failure and extending their lifecycle.

In contrast, approaches like analyzing components after destruction or performing tests that lead to failure do not align with the fundamental principles of NDT, which aims to preserve the integrity and functionality of the materials being tested. Similarly, while enhancing material properties can be a goal in some contexts, it does not directly relate to the primary objectives of non-destructive testing practices.
