Detecting cracks in metal
Webof refractive crack detection is based on the scattering of x-rays at the phase bounda-ries of different materials or gaps. The sensitivity for cracks is nearly independent of the crack width and it is independent from the spatial (scanning) resolution of the system, because the integral scattering intensity is a measure of the total crack den- WebSep 1, 2006 · AC lends itself very well to surface and shallow crack detection, about .100″ to .250″ below the surface of the metal. DC creates a field that flows through the part, not just along the surface. This allows …
