Hi guys,
First post and not sure this is the place but,
I am looking at a weld flaw between two plates butt welded together.
I have reviewed the asme IX and bs 7910 and I am confused slightly about planar/non planar classification.
Basically the flaw in question is behind the weld in one the plates. The flaw is similar to a sub surface crack therefore with length 23mm and depth into the thickness of 3.6mm
However the flaw is not strictly a crack as a depth of 5mm has been identified, this dimension is perpendicular to the length in 2d looking onto the surface if that makes sense!
Can i just treat the flaw as l = 23 and a = 3.6? ignoring the 5mm?
It is effectively a 3d rectangular prism and it is perfect aligned with the axis of the plate, therefore not really non-planar.
Any help much appreciated
