Full radiography is equivalent to RT-1 stamping as defined in UG-116. As you can see, butt welds in small (not exceeding 10"), thin wall nozzles are not required to be RTed.
100% RT means all butt welds, including those in small nozzles will have radiography examination in full length. This is not a code requirement. It is usually a service requirement. Vessels in wet H2S service often require 100% RT.
Full radiography need not be 100% See UW 11(a)(5)(b).

--Dear All,
Could you please tell me what is the difference between 100% radiography & fully radiography? Is it clarified in ASME code?
Thanks,
