What is the purpose of non destructive testing?

• A. To detect weld defects without destroying the material
• B. To measure tensile strength
• C. To test corrosion resistance
• D. To inspect surface finish

Answer: (A)

Non-destructive testing is about evaluating a component’s quality and integrity without causing any damage, so you can identify flaws while the part remains in use or can be repaired without being destroyed. The main goal is to detect defects or discontinuities, such as weld defects, that could affect performance, allowing informed decisions about acceptance, repair, or rejection without destroying the item. That’s why detecting weld defects without destroying the material is the best choice. Measuring tensile strength, on the other hand, requires pulling a specimen to failure, which is a destructive test. Corrosion resistance and surface finish can be assessed by various methods, but they are not the primary purpose of NDT; those areas are addressed by tests and inspections that may be destructive or highly specific to the property being evaluated.
