What advantage does phased array technology provide in Eddy Current Testing?

Phased array technology significantly enhances Eddy Current Testing by allowing for the simultaneous acquisition of multiple signal data points. This capability stems from the use of multiple coils and electronic control mechanisms that can vary the angle of detection. By adjusting the timing of the signals emitted from the different coils, the testing system can focus on various areas of interest in real time, providing a comprehensive analysis of the material being inspected.

This results in a more efficient testing process as the data from multiple angles can be collected at once, leading to faster inspections and a more thorough evaluation of potential flaws. The ability to gather extensive data in a single pass opposed to sequentially scanning the surface also improves the accuracy and reliability of the inspection results, making it a powerful advancement in non-destructive testing methodologies.
