NDT inspection of fillet weld on curved surface
Hi,

We are having a fillet weld after curved surface instead of straight plate. Plate curvature radius is 2" . Can any one suggest any NDT technique?

Since your testing a fillet weld i would guess only MT. However it depends on the extent of testing, procedure, Material and so on...

Typically perform a visual examination along with a Magnetic Particle or Liquid Penetrant examination, depending on the material.

As well as a surface ndt examination - MT for ferrous material or PT for non-ferrous material, a visual examination would be very useful, you will be able to see whether the fillet weld is large enough according to specification and a control on the welding parameters will ensure that the weld complies with the WPS.

hello guys,

Thanks for your prompt responses. Actually i forgot to mention that the material is SS 316. Also we are suspecting root crack due to thermal fatigue and we have only one side access.

RT or UT are really the only options then.
If UT, draw a 1:1 sketch of part to see what UT technique to use, your level III should be able to answer that question if you can't
