Comparison of Scanning-Type Magnetic Cameras for Heat Exchanger Tube Inspection and their Applications
In this study, bobbin-type magnetic cameras for nondestructive inspection of small diameter tubes are reported. Two types of magnetic cameras were used to image eddy currents using exciting coils and annularly arrayed magnetic sensors, in order to detect and evaluate defects. The performance of both magnetic cameras was compared and verified using artificial defects introduced into the tubular test specimen of austenitic stainless steel 304 with 13.3 mm inner diameter.
