Dear Friends Construction code of a fabricated vessel is ASME Sec. VIII Div.1. WPS, PQR and WPQ have to be qualified as per ASME Sec. IX. MOC is SA516Gr.70. Now during running the PQR test does the TPI have to verify the base material TC of the PQR test coupons or any stamp transfer has to be checked before welding.. Also similarly during Welder qualification do we have to verify the base material TC or any stamp transfer checking for material identification. I think for PQR it is mandatory, but not for WPQ. Please provide code reference and in which clause this is given in AMSE Sec.IX that base material traceability is required before PQR and WPQ test. Regards Prem Nautiyal Cell: 9769316004 |
