NDE requirement for Structural steel

[salmon2]

Is it common to require NDE, surface and vometric, for structural steel, say astm a36, a992, a572, etc?
I personally think it is a good idea to have them, but don't know if it is too much. Thanks a lot.

It depends on end use of these materials. Typically, volumetric examination is done to look for plate laminations, and that is about it.

Volumetric examination is usually required for CJP (full penetration welds) on structural welding in lieu of X-ray. Part of the procedure to do a shearwave examination is to check the plate or structural member that is welded for lamination that could have propogated into the weld.

NDE depends upon the requirements of the Engineer (designer) of the product.
