NDT

We offer wide range of types of Non-Destructive Testing

Types of NDT

Visual Testing (VT)

The most widely used and oldest method. It involves an inspector looking at the surface for cracks, corrosion, or misalignment.

Best for: Finding large surface defects and ensuring overall quality.

Ultrasonic Testing (UT)

Short & Long, Uses high-frequency sound waves to "see" through a material. A transducer sends sound into the object and listens for echoes that indicate internal flaws or thickness changes.

Best for: Inspecting internal welds, finding hidden cracks, and measuring wall thickness.

Radiographic Testing (RT)

Similar to a medical X-ray, this uses X-rays or Gamma rays to produce an image of the internal structure of a component.

Best for: Detecting internal porosity, inclusions, and cracks in dense materials like steel.

Magnetic Particle Testing (MT)

A magnetic field is applied to a ferromagnetic part, and iron particles are spread over it. The particles cluster around any cracks where the magnetic field "leaks" out.

Best for: Detecting surface and near-surface cracks in steel parts.
MFL is an advenced type of MT

Eddy Current Testing (ECT)

Uses electromagnetic induction to detect surface and sub-surface flaws in conductive materials.

Best for: Detecting thin surface cracks and measuring coating thickness on aerospace components

Liquid Penetrant Testing (PT)

A colored or fluorescent dye is applied to the surface. After a "dwell time," it is wiped off, and a developer is applied to draw out the dye trapped in tiny surface-breaking cracks.

Best for: Finding surface cracks in non-porous materials like aluminum, stainless steel, and ceramics
