Ultrasonic Testing (UT)

Ultrasonic Testing (UT) is a Non-Destructive Testing (NDT) method that detects not only surface flaws but also internal defects. By using high-frequency sound waves, UT provides accurate insight into the integrity of materials without causing any damage to the object.

How UT Works

• A transducer transmits high-frequency sound waves into the material.
• Waves reflect off internal surfaces and flaws.
• An A-scan display shows the time for waves to return, locating and sizing defects.
• Flaws are analyzed for depth, orientation, and severity.
• Wall thickness of pipes, tanks, and vessels can also be measured.

Applications

• Weld Inspection – detect cracks, porosity, inclusions, and lack of fusion.
• Casting Inspection – identify shrinkage cavities and internal voids.
• Corrosion Monitoring – measure wall thickness in pipelines and vessels.
• Composite Materials – verify bond integrity in aerospace and automotive parts.
• Infrastructure – inspect bridges, cranes, and heavy steel structures.

Benefits of UT

• Detects internal flaws invisible to surface methods.
• Provides accurate, quantitative defect data.
• Non-damaging to the inspected object.
• Excellent sensitivity with deep penetration.
• Portable and safe, no radiation involved.
