To your knowledge , is there any difference between "Full Radiography " and "100% Radiography"

I believe for pressure vessels go to ASME VIII UW-11. Joint category or joint efficiency.

Spot: A % of the total lenght of the weld.

Full: 100% of the welds made.

No, full radiography is the same as 100% radiography. If you're speaking of a pressure vessel built to ASME VIII, the joint efficiency will be 1 (one) or 100%.

Also a pressure vessel built to ASME VIII Div 1 may have a JE of 85% (see UW-12) in which case you use Spot RT which in this case is not to be construed as 85% RT.
