General:
Since PWHT is an essential variable, the note in the WPS that "WPS has note - this WPS is qualified with and without PWHT" is not acceptable.
1) whether the above WPS can be accepted based on the 3 supporting PQR'S.
WPS can be accepted based on WPS # 2 & 3.
2) Whether A SINGLE WPS can be qualified with and without PWHT by supporting PQR'S with and without PWHT.
No.
3) What will be the thickness range qualified based on the actual thickness of base metals used in PQR Qualification. i think qualified base metal thinkness range will be 10 to 20mm as impact testing is done.
Qualified base metal thickness range is 1.5 to 20mm.
4) whether two diffrent filler metals such as E6010 and E7018 can be mentioned on single WPS.
Yes.
5) Whether WPS without impact testing and PWHT can be qualified with PQR having impact testing and PWHT.
No
6) Whether the above WPS can be used for welding any ASME P1G1 Material together or to an ASME P1G2 material as required.
Yes for P1G1 material together and No for P1G2 material.

--Dear All,Greetings.I have to reveiw a WPS which involved welding by SMAW process. WPS has two filler metals E6010 and E7018 mentioned seprately in filler metal section(QW-404).WPS dont require any impact testing. WPS has note - this WPS is qualified with and without PWHT.three PQR are supporting the above WPS. Detailed as below.1) PQR is welded by using base metal, P1G1 TO P1G1(SA 516 GR 60 TO SA 516 GR60) . filler metal used is E7018. Thickness of base metal used for PQR Qualification is 10 mm. impact testing is done for this PQR.2) ) PQR is welded by using base metal, P1G1 TO P1G1(SA 516 GR 60 TO SA 516 GR60) . filler metal used is E6010. Thickness of base metal used for PQR Qualification is 10 mm. impact testing is done for this PQR. Also PWHT is carried out at 1150 deg. F for 6 hours.3) PQR is welded by using base metal, P1G1 TO P1G2(SA 516 GR 60 TO SA 516 GR60) . filler metal used is E7018. Thickness of base metal used for PQR Qualification is 10 mm. impact testing is done for this PQR. Also PWHT is carried out at 1150 deg. F for 8 hours.my question is1) whether the above WPS can be accepted based on the 3 supporting PQR'S.2) Whether A SINGLE WPS can be qualified with and without PWHT by supporting PQR'S with and without PWHT.3) What will be the thickness range qualified based on the actual thickness of base metals used in PQR Qualification. i think qualified base metal thinkness range will be 10 to 20mm as impact testing is done.4) whether two diffrent filler metals such as E6010 and E7018 can be mentioned on single WPS.5) Whether WPS without impact testing and PWHT can be qualified with PQR having impact testing and PWHT.6) Whether the above WPS can be used for welding any ASME P1G1 Material together or to an ASME P1G2 material as required.Awaiting your valuable reply.Thanks in advance.RegardsAsad Azmi
