Description

Eddy current testing is a widely used nondestructive testing method, especially for inspecting steam generator tubes in nuclear power plants. Due to the complex nature of this technique, the analysis of inspection data is a difficult task requiring a great deal of work by experienced human analysts. This is time consuming, expensive, and can be inconsistent due to human nature. Also, the presence in eddy current signals of interference from the tube support plates and deposits can make the data very difficult to analyze. To help overcome these obstacles, an automatic eddy-current analysis system is needed to aid the analysts.
