What is Non-destructive testing?

Non-destructive testing is a technique to find out fine defects without breaking parts, etc. to prevent accidents before they happen.

Non-destructive testing is a technique to find out fine defects without breaking parts, etc. to prevent accidents before they happen.
It plays an important role at various sites of quality control such as automobile, railway, aircraft, bridge, power plant, chemical plant, etc.
Meanwhile, there are various methods for the non-destructive testing.
Please refer to the information below, as the suitable inspection method varies depending on type of defect and material, etc. desired for inspection.
If you are not sure, please feel free to contact us.
