Hello Junho, CW Method is still beyond ASME considerations. You should to check the 2007 edition. But you can write to Ed Ginzel or to Mark Davis. They are part of this forum and is sure they know...

Mr Park
ASME does not describe the "so-called" creeping wave. When you examine the arrival times of the signals when peaking a small depth notch on the opposite wall it will be seen that the detection is actually achieved by the shear headwave. This can be done using a refracted compression mode at some angle between about 70° to 80°
Good description can be found on the application of the techniques in general on http://www.ndt.net/article/pow1297/schmid/schmid.htm

nresolved asset integrity problem in the industry. Current methods for measuring wall thickness with liftoff, without removing insulation, all have severe limitations. Eddyfi introduces Lyft — a reinvented, high-performance pulsed eddy current (PEC) solution. The patent- pending system features a state-of-the-art portable instrument, real- time C-scan imaging, fast data acquisition with grid-mapping and dynamic scanning modes, and flexibility with long cables. It can also scan through thick metal and insulation, as well as aluminum, stainless steel, and galvanized steel weather jackets. Who else but Eddyfi to reinvent an eddy current technique and redefine CUI programs. Got Lyft?
