I have an item that was to be match drilled. It ended up not being match drilled. Now I have some 1 1/2" mislocated holes. We are allowed to plug weld and UT per engineer. My question is, per AWS D1.1(06)5.26.5 (2) (b) the repair is to be verified by the same means as specified in the contract documents (UT) and approved by the engineer, is UT of plug welds covered by 6.20.1 "groove welds"? or is a procedure needed for testing of plug welds?
