[MW:10390] WQT

Dear experts,
 
              Good day for all. While qualifying performance qualification for the welder with
3F and 4F fillet welds, I had noticed lot of undercuts and poor weld profile so I have rejected 4F piece. But 3F weld somewhat ok and its accepted.
 
I have to qualify this welder as per section IX. As far as performance qualification is concerned if the one piece is failed the entire qualification test is failed.But our contractor insist me to accept 3F. Should I reject both pieces or reject only one which is failed.
 
Kindly someone correct me if i am wrong and if possibel refer the para in section IX or from
QW-300 of section IX.
 
Thanks and regards
Raja K
