Re: [MW:19116] Re: Comparision of UT & RT ( Justifying UT )

Dear Sam,

RT cannot detect planar defects parallel to the direction of incident radiation or in other words the probability of detection is less, but  the defects perpendicular to the radiation can be radio-graphed.

Meanwhile, the specimen or test-piece can be reoriented and re-shot, so as to get the optimum results by detecting the so called parallel defects from the different beam incident angle.

And this is not the scenario in case of real-time radiography.

dear sir,

just confusion, i think in RT we can detect planar flaws which are parallel to x-ray beam and can not if not parallel ?

pls clarify me.

Dear Steven ,  by RT you cant detect planar flaws parallel to xray beam and UT is very usefull with its flexible usage and cost efficency , pls tell me about what type of alloy and welding method used at to be controlled  welds i may inform you more details for UT , and if you have any doubt about the NDT personel tell them on any problem of work they will have legal problems if they have any major mistakes on controls .
