NDT Basics
NDT Basics
Non-Destructive Testing (NDT), encompasses a group of analysis techniques used to evaluate the properties or conditions of a material, component, or system without causing any damage to it.
NDT is favored for its cost-saving potential, as it avoids material wastage and replacement costs. It ensures safety by allowing defect inspections without disassembly and is versatile enough for various applications, from aircrafts to pipelines. Some NDT methods also offer immediate insights, enabling prompt action.
NDT is crucial in ensuring the safety, quality, and longevity of various sectors. It aids in early defect detection, guarantees product standards, supports regular infrastructure monitoring, and helps extend the lifespan of components by addressing issues promptly.
NDT Processes
NDT Processes
Some of the most common NDT processes and methods are:
Visual Inspection (VI): Direct visual observation to detect any abnormalities or defects.
Liquid Penetrant Testing (PT): Uses a dye solution to highlight surface defects.
Ultrasonic Testing (UT): Uses high-frequency sound waves to detect defects or measure material thickness.
Magnetic Particle Testing (MT): Used for ferromagnetic materials, it detects surface and subsurface discontinuities by using magnetic fields.
Eddy Current Testing: Uses electromagnetic induction to detect defects in conductive materials.
Radiographic Testing (RT): Employs X-rays or gamma rays to view the inside of a component, similar to a medical X-ray.
