What can the introduction of noise in Eddy Current Testing lead to?

The introduction of noise in Eddy Current Testing can significantly affect the quality of the testing process, leading to reduced accuracy and reliability of results. Noise can obscure the signals generated by flaws in the material being tested, making it difficult to distinguish between legitimate indications of defects and interference from external factors. This can result in false positives or missed defects, directly impacting the integrity of the test results.

In contrast, other outcomes such as decreased testing duration, improved sensitivity in flaw detection, or increased equipment lifespan are not associated with the introduction of noise. In fact, noise typically necessitates longer testing durations as technicians may need to repeat tests or utilize more complex analysis techniques to filter out the unwanted interference, further emphasizing that noise is detrimental to the process. The understanding of how noise interacts with the signals in Eddy Current Testing is crucial for maintaining high testing standards and ensuring accurate evaluations.
