Alternating current field measurement : ウィキペディア英語版 | Alternating current field measurement
Alternating Current Field Measurement (ACFM) is an electromagnetic technique for non-destructive testing detection and sizing of surface breaking cracks. It was derived from the methods used in eddy-current testing and works on all metals, ferrous or non-ferrous. Since it doesn't require direct electrical contact with the surface it can work through coatings such as paint or rust. ==Use== The system was originally developed in the early 1990 for the sub-sea and topside inspections of offshore structures without the need to remove the item's protective coating. Since then it has been successfully applied to onshore process plants. Applications include in-service inspection of welded items and crack detection in vessels.
