Question

Which of the following is NOT a non-destructive testing?
1. X-ray test
2. Magnetic particle test
3. Dye penetrant test
4. Nick break test

Answer 1

Correct Answer - Option 4 : Nick break test

Explanation:

• There are two different types of testing welded joints:

1. Destructive test: Welded sample coupons are tested and the part after the testing cannot be used.
   • Tensile testing
   • Hardness test
   • Bend test
   • Impact test
   • Nick break test
   • Acid etch test
2. Non-destructive testing (NDT) is the process of inspecting components for discontinuities or differences in characteristics without destroying the serviceability of the part or system.
