How are defects characterized further after detection through Eddy Current Testing?

The detection of defects through Eddy Current Testing is an important step in the non-destructive testing (NDT) process, but further characterization is often necessary to fully understand the nature and extent of those defects. Utilizing ultrasonic testing or radiography allows for a more detailed analysis.

Ultrasonic testing employs high-frequency sound waves to penetrate the material and capture information about the defect's size, shape, and orientation. This method is particularly effective for locating internal flaws and provides depth information, which Eddy Current Testing alone may not adequately resolve.

Radiography, on the other hand, uses X-rays or gamma rays to reveal the internal structure of materials. This can reveal not just the presence of defects, but also their specific characteristics in a visual format. Both of these methods complement Eddy Current Testing, allowing for a comprehensive assessment.

While other options may involve additional methods of analysis, the combination of ultrasonic testing or radiography provides the depth of information necessary to further characterize defects discovered through Eddy Current Testing, making it the best choice for a thorough evaluation.
