NDT
NDT (nondestructive testing), also referred to as NDE (nondestructive examination) and NDI (nondestructive inspection), is a family of specialized technical inspection methods which provide information about the condition of materials and components without destroying them.
NDT examines actual production pieces and reveals the presence of flaws which can be evaluated against accept/reject criteria. It is one of the major tools of quality control and is firmly entrenched in quality programs of industries such as aerospace, automotive, defense, pipe line, power generation, preventative maintenance, pulp and paper, refinery, and shipbuilding.
There are several established NDT methods currently in industrial use. New methods are being constantly researched and developed, and many of the established ones have their effectiveness and efficiency enhanced by conversion to electronic, computerized, or robotic operation.
Forming the core of NDT are five basic methods: Liquid Penetrant Testing (PT), Magnetic Particle Testing (MT), Radiographic Testing (RT), Ultrasonic Testing (UT), and Eddy Current Testing (ET)

1- Conventional NDT (Non-Destructive Testing)
Utilizing traditional methods to detect defects and irregularities without causing damage to the materials.
Visual Inspection (VT)
All manufacturing, Processing, Welding using suitable measurements tools to verify the quality of the products according to applicable documents.
Liquid Penetrant Testing (PT)
Uses a liquid dye to reveal surface-breaking defects by highlighting them under UV light or visible light.
Magnetic Particle Testing (MPT)
Detects surface and near-surface defects inferromagnetic materials using magnetic fields and iron particles.
Ultrasonic Testing (UT)
Employs high-frequency sound waves to detect internal flaws within a material.
Radiography Testing (RT)
Utilizes X-rays or Gamma-rays to view the internal structure of a component, identifying internal defects.
Vacuum Test
Checks for leaks in a component by creating a vacuum and observing for pressure changes.
Pressure Vessel Inspection
Involves various NDT methods to ensure the integrity of pressure vessels.
Thickness Measurement & Dry Film Thickness (DFT)
Measures the thickness of materials, often using ultrasonic methods.
Hardness Test
Determines the hardness of a material, which can indicate its strength and wear resistance.
Replica Test
This method statement covers the replication of surface microstructures of items where sectioning is not allowed. In other words it is nondestructive technique. This usually involved bag items or crucial items which cannot be removed from its location.
Holiday Detector
Used to detect defects or discontinuities in coatings, such as pinholes, pores, or cracks, by applying a high-voltage electrical spark.
Ferrite Test
Typically involves measuring the ferrite content in materials, such as stainless steel or duplex steel.
