transverse flaws such as lack of fusion and cracking in rail can only be located at teh top and bottom surfaces with a 45 degree wedge, and somewhat with a 70 degree. To be able to detect transverse flaws at other locations a 45 degtree tandem probe technique does well.Set pitch-catch signal to middle of crt screen.Fusion flaws in the rail head are best detected by using a pitch catch mode using two 45 degree wedges on opposite sides of the railhead. Hope this helps somewhat Give it a try.

Are you looking for a system? What type of rail are you inspecting? New or used? I have just completed the installation of a large system to do complete inspection of rails. It uses wheels located to inspect the various parts of the rail, i.e. head, flange, web, using a variety of transducers. A picture of it can be found on my website at

Pitch catch and through transmission might work. Angle beam in one direction will only redirect reflected waves if indications are encountered on the fusion line. Are these new welds in rails?
