[MW:3593] Fw: [MW:3578] WPS/PQR

Dear all,
the PQR can be used without any change but you must make a new revision of your WPS
and the limits will be from 1.5 or 5 mm  to 2T according to the thickness of PQR piece and all suplementary essentioal value will be non essentional

Best Regards ,
ENG. Ahmed Osman

Dear All
I have question regarding WPS/PQR matter. I have one qualified WPS/PQR (GTAW/SMAW) which the base metal spec. is SA 333 Gr. 6 and was impact tested at -50C. Can this PQR support a new WPS to weld SA 106 Gr. B without impact test(not required by code) . What will be the ranges of qualification? is it i need to remove the impact test result on old PQR and allowed by ASME IX code? Please help me. Thank in advance
Regards
