Mechanical testing is carried out on a sample to find if the weld area / HAZ area meet the required/ declared mechanical properties. If you have to carry out a nick break test then this defect may be a prime reason for the sample not meeting the required mechanical properties which may eventually lead to rejecting the sample test results.

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.
