ASME Section VIII Div I: Repair - Rewelding of A Coupon Back onto A Pressure Vessel
(OP)
I am seeking guidance for acceptable repair to a pressure vessel. In this instance, a fabrication shop punched a hole in the wrong spot of a pigging barrel (see attached picture). After notifying 3rd party inspection, they took the plug (same material grade, composition and thickness) beveled it back and shot 100% x-ray on the repair spot. Additionally they did a 14 hour hydro test at 1800 PSI on the vessel (1.5 x design).
I'm coming up short for answers when searching ASME Section III Div I. Is this an acceptable repair? If not, what, if anything, is considered acceptable?
Greatly appreciated.

Unfortunately the repair in your picture looks not good at all, as the owner I would not be happy.

SnTMan: That was also the only relevant section I could find as well. I agree, it looks like poor workmanship.
Thank you both for your replies!
