Please I want to make some repairs inside a Pressure Vessel in order to restore its base metal thickness. I didn't find nothing specific in ASME IX to qualify it. May I use the same WPS used for standard butt weld done on it. Thanks, any input is appreciated in advance.
If the vessel has a code stamped name plate and if the owner wishes to retain the code status of the vessel, the repairs must be carried out in accordance with the National Board Inspection Code and the repairs must be performed by a company that has an "R" stamp.
