NDT Inspection & Testing

NDT Terminology

NDT 101

  1. Advanced Ultrasonics: This involves using more sophisticated ultrasonic techniques and equipment for inspecting complex geometries and critical components.
  2. Digital Radiography: The use of digital imaging techniques for radiographic testing, which offers improved sensitivity and resolution compared to traditional film-based methods.
  3. Eddy Current Testing (ECT): ECT is widely used for surface and near-surface defect detection, and advancements in probe design and signal processing have increased its applicability.
  4. Phased Array Ultrasonics: This is a specialized ultrasonic testing technique that employs multiple small ultrasonic elements to steer and focus sound waves, allowing for rapid scanning and defect characterization.
  5. Computed Tomography (CT) Scanning: CT scanning is a powerful technique that provides 3D images of internal structures, making it valuable for inspecting complex components and composite materials.
  6. Infrared Thermography: This technique uses thermal imaging to detect variations in temperature, which can indicate defects or anomalies in materials.
  7. Acoustic Emission Testing (AE): AE is used for continuous monitoring and detection of active defects, crack growth, or structural integrity of components under stress.
  8. Guided Wave Testing (GWT): GWT is used for long-range inspection of pipes, plates, and other structures, allowing for the assessment of large areas from a single probe position.
  9. Electromagnetic Testing (ET): ET includes methods like Magnetic Particle Testing and Eddy Current Testing, which are used for surface and subsurface defect detection.
  10. NDT in Additive Manufacturing: With the growing use of additive manufacturing (3D printing) in various industries, there is an increasing demand for NDT techniques to ensure the quality of printed components.

What is Nondestructive Testing?

Nondestructive Testing (NDT) is a "health checkup" for materials, components, or entire systems, such as pipelines, bridges, aircraft NDT is commonly used in forensic engineering, mechanical engineering, petroleum...
