Subject: [MW:8399] Defect in PQR Specimen

Anyone, Can u plz give your opinion,
 
PQR qualification of SS pipe, 30" x 15.88 mm thik pipe by SMAW+SAW process, In RT defect observed in 200 mm length which is not acceptable as per Sec IX. But rest of the portions are without any significant defects.
 
Can we proceed with the Mechanical testing after discarding the defect area or is it required to Repair & Re-RT to be done in the defect area before taking the specimen for mechancial testing.....  Plz clarify.
