NDE percent
NDE percent
(OP)
most of the codes such as ASME secI have cleared that the NDE shall be done on the "entire" weld.but in ASME B31.1 I couldn't find this word. so what shall we do about this?
does this mean that we can choose the percent for it or not?

RE: NDE percent
xray 10% of each welders welds, if 10% fail then an additional 20% should be xrayed, if you still get failed welds then 100% xray would be implemented.
however, after the first set of failed welds the particular welder would be disqualified and the process started over with the new welder.
RE: NDE percent
From an inspectors point of view, when I see a reference that a weld is to be subjected to NDE, unless otherwise specified, I assume 100% coverage. This would be the safest route to take. Discuss it with your inspector, if you have one, or your customer/end user.

RE: NDE percent
Now that I'm next to my codebooks, paragraph 136.4.1 and Table 136.4 of Chapter VI of the 1998 Edition of B31.1 addresses required NDE.
