What factors must be analyzed to determine if a defect is critical after detection via Eddy Current Testing?

To determine if a defect detected by Eddy Current Testing is critical, it is essential to analyze multiple factors, including the size, location, and orientation of the defect, while also taking into account the service conditions of the component in question.

The size of the defect is important because larger defects typically pose a greater risk of failure. However, knowing the location is equally crucial, as defects in high-stress areas may have more severe implications than those in less critical areas. Additionally, the orientation of the defect can influence how it may propagate or affect the structural integrity during normal operation.

Moreover, service conditions—such as the operational environment and the loading conditions—play a significant role in assessing the criticality of a defect. For instance, a defect in an area subjected to high stress or fatigue may be considered more critical than a similar defect in a less stressed area, regardless of size.

Hence, a comprehensive analysis that encompasses these aspects provides a better understanding of the potential risk posed by the defect, guiding necessary maintenance or operational decisions. This holistic approach is essential in ensuring safety and structural integrity in the components being inspected.
