In Situ Inspection of Fasteners for Detecting Small Cracks

Conference ·
OSTI ID:950194

An in-situ bolting and fastener inspection system has been developed by PNNL under funding from the Department of Energy. The inspection system utilizes an ultrasonic pulse-echo technique to detect very small cracks emanating from the thread root. The primary benefits are the ability to inspect the fastener without its removal, much improved detection sensitivity to small cracks and the intuitive interpretation of the acquired images.
