Eddy current flaw detector
Eddy current testing is one of the many non-destructive testing (NDT) methods, which applies the fundamental theory of electromagnetism as the basis for conductor testing.
The advantage is 1. Sensitivity to small cracks and other defects
2. Fast detection speed and high sensitivity for surface and near surface defects
3. The test results are real-time
Therefore, it is commonly used to detect workpieces with complex structural dimensions.
