Looks like a forging in a pressure vessel?
Are you making and supplying new forgings, or is this a maintenance repair ?

The ASTM spec likely has some pretty specific info about weld repairs.

No mention of "high temperature" or "boiler" in the OP or the A66 summary so the ASME BPVC // may //not need to be invoked this time .

dear Tmoose
it is a repair on a tube sheet of shell and tube heat exchanger that damaged due to a bad cutting process of tubes by cutting blade.
