We have to do additional test plate for repair welding if we have used a qualified welding procedure to perform the repair welding?

RE: Repair Welding in ASME VIII vessel.
In general repairs made with an appropriately qualified WPS are acceptable.
Is the vessel subject to UG-84 (i)?
RE: Repair Welding in ASME VIII vessel.
I can confirm that the UG-84 is applicable to the vessel.
We can inform that the vessel in fabrication is a Duplex Stainless Steel, where we have qualified some WPS and have tested some test plates according to each WPS used. Our question is about the specific requirement made by the TPI, who ask us to perform a specific test plate, not take in accouting that we had made all the test plates during the production welds.

Only exception would be for Controlled Deposition procedures, where bead placement and heat input are critical items.
