NDT Solutions FAQ
Why is NDT important?
Nondestructive testing (NDT) is important because it helps ensure safety and reliability across a range of industries. Using NDT equipment such as flaw detectors, you can locate and size surface and subsurface flaws and defects in material. For example, this can be done for steel used in the engineering and construction of bridges, aircraft, motor vehicles, pipelines, and more. Hidden deficiencies can cause substantial risk to safety, so using NDT to help ensure maximum performance over time is important.
How do different NDT techniques work?
Olympus specializes in five frequently used nondestructive testing (NDT) methods: eddy current, eddy current array, conventional ultrasonic, phased array, and phased array using the total focusing method (TFM)/full matrix capture (FMC).
- Eddy current: Uses electromagnetic induction to detect and characterize surface and subsurface flaws.
- Eddy current array: Provides the ability to electronically drive multiple eddy current coils for enhanced speed and data quality.
- Ultrasonic: Uses short ultrasonic pulse waves to detect internal flaws or characterize materials.
- Phased array: The beam from elements can be electronically steered, focused, and scanned with a single transducer assembly.
- TFM/FMC: With FMC, a single element is pulsed and all the other probe elements receive the reflected signals; this process repeats for all elements. TFM is the data processing method.
Can NDT be used to detect damage mechanisms and evaluate a material’s remaining life?
NDT methods can be used to identify and detect multiple damage mechanisms occurring over time, such as:
- Corrosion
- Cracking
- Stress corrosion cracking (SCC)
- Wet hydrogen sulfide (H2S)
- Common damages like blistering
- Stepwise cracking
- Hydrogen-induced cracking (HIC)
- Stress-oriented hydrogen induced cracking (SOHIC)
- Sulfide stress cracking (SSC)
- High temperature hydrogen attack (HTHA)
- And many others
For most of these damage mechanisms, NDT methods such as ultrasonic testing or eddy current testing (ECT) provide quantitative information to help calculate the remaining life of components or monitor known existing flaws over time (i.e., damage evolution).
