[MW:22968] PQR without impact test

By Materials & Welding
 Dear expert ;

we have a WPS and PQR for A333 Gr 6 welded with ER 70S-3 and E7018 , the mechanical test in the PQR are only tensile test and bend test.

Our client didn't accept the PQR because is missing impact test and he ask to repeat all the PQR with all mechanical test ( with ER70 S-6 for better impact test result ).

it's possible to keep the PQR and to make only the impact test ( we can weld a 6" pipe according the WPS but with ER 70 S-6 and take specimens for impact test ). ????

Regards
