Sammy,
Of course repair can be done, and are done every day.. As long as it is within the scope of the procedures. Now there are exceptions of course, but one shot deals are rather uncommon.
Every weld you do should have a welding procedure specification (WPS) and each WPS should have a procedure qualification record (PQR) to back it up... Your WPS's and PQR's should have specific repair instructions that detail what is to be done that include defect limitations.
If your facility is doing the welds in conformance with D17 than you should have qualified these fabrication procedures and included repair/rework into the scope of the PQR's and WPS's as they apply to specific componant design specifications, details and scope.
You should have class 1 doccuments for repair that refer to the specific part number of your component, and that class 1 doccument should have plainly stated criteria as to limitations of defects that are repairable or not repairable.
Your own in house doccumentation should cover this and be informed by the vendors standard practice manual.
Who qualified your in house procedures? They should be the first person you approach on this issue.
