Radiographic Testing (RT) is a powerful non-destructive testing (NDT) technique that uses X-rays or gamma rays to inspect the internal structure of materials, welds, and components. It helps in detecting subsurface and volumetric defects that are not visible on the surface—without causing any damage to the material.

At Lady Dona Infra Projects Limited, we use cutting-edge radiographic equipment and highly trained RT Level II and III professionals to ensure safe, accurate, and code-compliant inspections.

🔬 How RT Works

1. Radiation Source: X-ray or gamma-ray is directed through the test object.

2. Film or Digital Detector: A film or digital sensor captures the transmitted radiation on the opposite side.

3. Image Interpretation: Defects like voids, cracks, or inclusions appear as variations in the image density and are interpreted by certified experts.

🔧 What Radiographic Testing Detects

• Porosity

• Lack of fusion

• Slag or gas inclusions

• Cracks

• Undercuts & voids

• Misalignments in welds

🏗️ Applications of RT

Radiographic Testing is widely used in:

• Pressure vessels

• Pipelines (oil & gas, chemical)

• Structural welds

• Castings and forgings

• Boilers and storage tanks

• Aerospace & automotive components

🧪 Types of Radiographic Testing Offered

• X-ray Radiography: Ideal for thinner materials and detailed internal images.

• Gamma Radiography: Used for dense materials and thicker components (using Iridium-192 or Cobalt-60).

• Digital Radiography (DR): Immediate image capture with digital processing for high-resolution flaw detection.

• Computed Radiography (CR): A hybrid method using reusable phosphor imaging plates.
