David,

Checkout Sec 2.18, which states "Fatigue categories B and C require that the Engineer ensure that CJP groove welds subject to cyclic transverse applied stress into the tensile range be inspected using RT or UT." 

Otherwise, it is up to the Owner's Engineer to must specify any additional NDE required or requested by the design, local or national government government codes or Purchasers requirememts.

Gary Martin

Chapter 17 of the International Building Code gives the requirements for inspections for building construction. Although not listed in the IBC, the old Uniform Building Code section 1703 gave requirements for NDE. All full pene welds were 100% tested with UT or RT. If a rejection rate of less then 5% was acheived for an individual welder, the inspection rate could be dropped to 25% after the welder had welded at least 40 welds on the project.
Now it is left up to the Engineer of Record for the project.

All we do here is D1.1 structural steel.  Generally speaking, we go by the requirements of the job specs.  But also, even if not called for by job specs, if it is supposed to be CJP, we figure the requirement is for a reason so I UT all CJP welds (except when told we do not need to) within the D1.1 5/16" to 8" range, and even some slightly below that.  That is for own comfort of mind and to push the welders to maintain a higher quality performance.  We have not RTed any welds here since I have been here.  But to answer your question, within the context of new construction and D1.1, I am aware of no document except those noted above.
