🔧 ULTRASONIC TESTING (UT)

Ultrasonic Testing (UT) Services in India

Ultrasonic Testing (UT) is a highly reliable non-destructive testing method used to detect internal defects and measure material thickness using high-frequency sound waves. This method is widely used in industries where internal integrity of components is critical for safety and performance.

Jagdamba Technology provides professional Ultrasonic Testing services for welds, pipelines, pressure vessels, boilers, headers, and structural components, ensuring accurate inspection without causing any damage to the material.

Principle of Ultrasonic Testing

Ultrasonic Testing works on the principle of sound wave reflection.
When ultrasonic waves are introduced into a material, they travel through it and reflect back when they encounter:

• Material boundaries

• Internal flaws

• Changes in material thickness

The reflected signals are received by the probe and displayed on the UT instrument, allowing precise interpretation of defects.

How Ultrasonic Testing is Performed

1. Surface Preparation
   The inspection surface is cleaned to remove dirt, grease, rust, or scale.

2. Couplant Application
   A suitable couplant is applied to ensure proper transmission of sound waves.

3. Probe Placement
   Straight beam or angle beam probes are placed on the surface depending on inspection requirements.

4. Signal Monitoring
   Sound waves are transmitted into the material and reflected signals are analyzed on the UT equipment.

5. Evaluation & Reporting
   Defects and thickness readings are evaluated as per applicable inspection criteria and recorded in the inspection report.
