Non-Destructive Testing (NDT) Overview
How NDT evaluates materials or components without intentionally destroying their serviceability.
Visual, penetrant, magnetic, ultrasonic, radiographic, eddy-current, acoustic and thermal methods.
How NDT evaluates materials or components without intentionally destroying their serviceability.
Direct and aided visual examination as the foundation of many inspection programs.
Surface-breaking indication detection on suitable nonporous materials.
Surface and near-surface discontinuity detection in suitable ferromagnetic materials.
High-frequency sound for thickness, flaw detection and material characterization.
Repeatable wall-thickness measurement at defined locations.
Electronic control of multiple ultrasonic elements to form and steer sound beams conceptually.
A high-level explanation of diffraction-based ultrasonic flaw sizing concepts.
How X-rays or gamma radiation can create images of internal features.
Digital detectors and computed radiography as alternatives to traditional film workflows.
Electromagnetic inspection of conductive materials and selected surface or tubing conditions.
Listen for transient elastic waves from active material or structural events.
Surface-temperature patterns for non-contact inspection and screening.
How pressure, vacuum, tracer or observation methods can reveal loss of containment at a high level.
Compare what visual, penetrant, magnetic, ultrasonic, radiographic and eddy-current methods can observe.
Mechanized scanning, encoded position and repeatable data acquisition.
