Ultrasonic Testing (UT) is one of the most reliable and versatile non-destructive testing (NDT) methods used to detect internal flaws, measure thickness, and assess material integrity without causing any damage. It uses high-frequency sound waves that penetrate the material and reflect back from discontinuities, revealing hidden defects deep inside components.

At Lady Dona Infra Projects Limited, we deliver accurate, code-compliant, and efficient UT inspection services performed by highly qualified UT Level II and III professionals using modern, calibrated equipment.

🔍 How UT Works

1. A high-frequency sound wave is introduced into the test material via a transducer.

2. The wave travels through the material and reflects back from any internal flaw or boundary.

3. The returning echoes are displayed on a digital screen and interpreted by experts.

🧪 What Can UT Detect?

• Internal cracks and voids

• Lack of fusion in welds

• Inclusions and laminations

• Corrosion and erosion

• Wall thickness reduction

• Bond integrity in composites

🏗️ Applications of Ultrasonic Testing

UT is used across multiple industries and materials, including:

• Steel structures and bridges

• Weld inspection in pipelines and vessels

• Castings and forgings

• Storage tanks and boilers

• Turbine blades and shafts

• Rail, aerospace, and marine parts

⚙️ Types of UT Services We Offer

• Conventional UT – Single-crystal or dual-element probes for flaw detection and thickness measurement

• Phased Array UT (PAUT) – High-resolution 2D imaging for complex geometries and critical welds

• Time of Flight Diffraction (TOFD) – High-accuracy flaw sizing technique for weld inspection

• Corrosion Mapping – Detecting and mapping material loss in pipes and tanks

• Thickness Gauging – Measurement of remaining wall thickness in service components
