Development of eddy current testing system for welding inspection

Non-Destructive Test (NDT) techniques are widely used in several industries since nowadays most of the modern structure are made from steel structures. NDT relates to the examination of materials for flaws without harming the object tested. Eddy Current Testing (ECT) technique is a nondestructive te...

Owing to the low noise of the Anisotropy Magneto resistive (AMR) sensor, the ECT system with the AMR sensor has an advantage of detecting deep and small defects in metal structures.
