Non-Destructive Testing (NDT) & Techniques

Non-Destructive Testing or NDT is a testing method used by the inspection industry to evaluate assets and infrastructure. It is non-destructive as it assesses materials and their flaws without causing damage or permanent alterations.

Non-Destructive Testing methods are conducted through various techniques and diversely applied across industries.

NDT analysis techniques are the methods that can be utilised for data collection during an inspection.

At Sonomatic, we use NDT methods including:

  • Automated Corrosion Mapping (ACM) – This form of NDT generates maps of materials and their corrosion through ultrasonic scanning.
  • Time of Flight Diffraction (TOFD) – TOFD is conducted by releasing sound waves into an asset and measuring the time they take to return and their amplitude.
  • Automated Pulse-Echo (PE) – This NDT method is a corrosion diagnostic technique that utilises short bursts of sound waves to identify abnormalities in metallic assets.
  • Phased Array Ultrasonic Testing (PAUT) – Ultrasonic testing utilises sound waves to detect corrosion within materials. This NDT technique utilises array transducers that pulse elements in a sequence called phasing.
  • Liquid Penetrant Testing (LPT) – LPT identifies cracks in materials by releasing dye into an asset and evaluating where the dye is drawn.
  • Dynamic Response Spectroscopy (DRS) – Dynamic Response Spectroscopy is an ultrasonic inspection that utilises ultrasound to penetrate challenging coatings.
  • Multi Skip/Chime/SCHEMATIC – These NDT techniques are a form of ultrasonic inspection which detects corrosion at inaccessible locations.
  • Computed Tomography (InspeCT) – The Computed Tomography (InspeCT) NDT technique utilises tomographic tooling, which allows the identification of abnormalities through 360-degree radiographs.
  • Long Range Ultrasonic Testing (LRUT) – Ultrasonic testing utilises sound waves to detect corrosion within materials. This type of NDT is utilised for long stretches of materials such as pipelines.
  • Visual Testing (VT) – Visual non-destructive testing is a method used to examine objects without moving or applying pressure to the asset. Inspectors conduct this type of inspection through the naked eye or by utilising lights, cameras, and other tools.
  • Electromagnetic Testing (ET) – This form of NDT is conducted by introducing electromagnetic currents and assessing their reactions.
  • Radiographic Testing (RT) – Radiographic NDT employs gamma or X-radiations upon assets to identify defects.
  • Eddy Current Testing (ET) – Eddy Current NDT is used to measure the intensity of electrical currents in a magnetic field.
  • Magnetic Particle Testing (MT) – Magnetic Particle Testing NDT is conducted by inducing a magnetic field and assessing disruptions in the flow of the magnetic field.
  • Acoustic Emission Testing (AE) – This NDT method identifies material defects by examining acoustic emissions realised through imperfections in the material.
  • Leak Testing (LT) – Leak testing identifies leaks through measurements taken with pressure gauges and listening devices.

NDT Applications

Each NDT technique can be applied to a variety of asset and infrastructure inspections.

NDT applications include:
