Dear,
We may use the same procedure for repairing the welds as per clause 328.6 ( If there is no special requirement from client), which say
328.6 Weld Repair
A weld defect to be repaired shall be removed to
sound metal. Repair welds shall be made using a welding
procedure qualified in accordance with para. 328.2.1,
recognizing that the cavity to be repaired may differ in
contour and dimensions from the original joint. Repair
welds shall be made by welders or welding operators
qualified in accordance with para. 328.2.1. Preheating
and heat treatment shall be as required for the original
welding. See also para. 341.3.3.
How ever this clause is applicable only for the systems which are not placed in service, Refer clause 300.
Intent of the Code
(1) It is the intent of this Code to set forth engineering
requirements deemed necessary for safe design
and construction of piping installations.
(2) This Code is not intended to apply to the operation,
examination, inspection, testing, maintenance, or
repair of piping that has been placed in service. The
provisions of this Code may optionally be applied for
those purposes, although other considerations may also
be necessary.
Regards,
CH V Ramana

Hi,
Do we need separate wps for repair or the wps we used in production will be sufficient as per ASME B31.3,
and using the PQR which used in production , can I qualify repair wps.
Thank you
