Re: Inspection of Pipes for cracks ch protocol that will tell you and others whether you have developed something worth using. With one of the inaccurate measures that have been traditional in NDT, people won't know much about that.
: Dear NDT gurus, : I'm an MSc Mechtronics student and my project is to : develop a sensor for NDT of a pipe for cracks/defects.
: Currently I'm using audible sound exciting circumferential : waves, trying to measure changes in amplitude/frequency. : Results are not very promissing.
: Any ideas about how to construct a sensor that : will be able to scan length of the pipe?
