Types of test in NDT

Question

Accepted Answer

Non-Destructive Testing (NDT) includes various types of tests to assess the integrity of materials or structures without causing damage.

Visual Inspection: Direct observation to identify surface defects or anomalies.
Ultrasonic Testing: Uses high-frequency sound waves to detect internal flaws or measure thickness.
Radiographic Testing: Utilizes X-rays or gamma rays to examine internal structures.
Magnetic Particle Testing: Detects surface and near-surface defects using magnetic fields and particles.
Liquid Penetrant Testing: Reveals surface-breaking defects by applying a liquid penetrant and developer.
Eddy Current Testing: Detects surface and subsurface defects by inducing electrical currents in conductive materials.
Acoustic Emission Testing: Monitors the release of stress waves to detect active defects or damage.
Thermographic Testing: Uses infrared imaging to identify variations in temperature and detect defects.
Leak Testing: Determines the presence of leaks or seal integrity in enclosed systems.
Vibration Analysis: Assesses the condition of machinery by analyzing vibration patterns.
