1.what frequency waves are used?
2.how is the frequency decided?
3.with tofd , what is the max -min thickness which can be inspected?
4.once the waves are transmitted , they reach the discontunity where they get reflected as well as diffracted.how do we differentiate between reflected and diffracted waves?
5.sorry, but i didn't get...what exactly the purpose diffracted waves surve..i mean howz it different from the reflected waves?...does it really make so much of difference?...
6.whick discontinuties can be detected with TOFD?....7.
7.how are the discontinuties identified ?...i mean how do we know whether it's is a lof,crack,or a blow hole?
8.can tofd be implemented using present conventional UT setup?
9.where can i find more detailed information in this regard?
