An Update on Automatic Positioning, Inspection, and Signal Processing Techniques in the RFC/NDE Inspection System
Scallop Centering — development of an automatic scallop centering routine makes scallop inspections reliable.
Soft Survey Mode — improvements have been made for fast peak detection.
Method 2 Select Mode — a fine flaw detection technique based on the acquired waveform.
Antirotation Window Inspection — a frequency select mode has been established for detecting flaws in antirotation windows.
Scaling of Flaw Depth — a scaling factor has been developed, based on Phase I Reliability Test data, which converts flaw signal amplitude into estimated flaw depth.
