Dear All, Lot of confusion still remaining even after many reply.So I deleted my extra queries for better clarification.Seniors, please advise me on this subject.It is most urgent. Design Code – ASME B31.3
Welding Code – ASME BPV SEC IX
I have a PQR for the following material classification as per ASME BPV SEC IX
Material Used for PQR – P1 Group No.1 To P1 Group No.2
Weld Metal Impact Tested – Yes PWHT done on weld metal - Yes 1. Can I weld P1 Group No.1 to P1 Group No.1 based on above supporting PQR(Suppose,I am following all essential variables as per above PQR)? 2. Can I weld P1 Group No.2 to P1 Group No.2 based on above supporting PQR(Suppose,I am following all essential variables as per above PQR)?

WPS can be used to weld P1 G2 to P1 G2. Please note that there is no P2 in ASME. Thanks & Regards, (karthik)

Date: Tuesday, October 26, 2010, 7:55 AM Aneesh, Regarding the Query No.2, the actual PQR is P1 G1 to P1 G2. So is it possible to weld P2 G2 to P2 G2 as per QW 403.5? You cannot weld P2 G2 to P2 G2 with existing P1 G1 to P1 G2 qualification Regards K.Babu

Karthik Sir, Regarding the Query No.2, the actual PQR is P1 G1 to P1 G2. So is it possible to weld P2 G2 to P2 G2 as per QW 403.5? Please correct me if I am wrong. Regards, Aneesh KSA On Mon, 25 Oct 2010 11:32:50 , Karthik wrote | Hi, .As per QW403.5 you can use.Please find below the answer for your quiries marked in RED. Quiery No.1 1. Is there any problem for welding P1 Group No.1 to P1 Group No.1 & P1 Group No.2 to P1 Group No.2 based on above PQR? QW403.5 For ferrous materials in table QW/QB-422, a procedure qualification shall be made for each P-Number Group Number combination of base metals, even though procedure qualification tests have been made for each of the two base metals welded to itself. If, however, two or more qualification records have the same essential and supplementary essential variables, except that the base metals are assigned to different Group Numbers within the same P-Number, then the combination of base metals is also qualified. In addition, when base metals of two different P-Number Group Number combinations are qualified using a single test coupon, that coupon qualifies the welding of those two P-Number Group Numbers to themselves as well as to each other using the variables qualified. This variable does not apply when impact testing of the heat-affected zone is not required by other Sections. Quiery No.2 2. Can I write separate WPS (with impact test) based on above PQR for, Material – P1 Group No. 1 to P1 Group No. 1 Material – P2 Group No. 2 to P2 Group No. 2 QW200.2 (f) Multiple WPSs With One PQR/Multiple PQRs With One WPS. Several WPSs may be prepared from the data on a single PQR (e.g., a 1G plate PQR may support WPSs for the F, V, H, and O positions on plate or pipe within all other essential variables). A single WPS may cover several essential variable changes as long as a supporting PQR exists for each essential and, when required, supplementary essential variable [e.g., a single WPS may cover a thickness range from 1⁄16 in. (1.5 mm) through 11⁄4 in. (32 mm) if PQRs exist for both the 1⁄16 in. (1.5 mm) through 14 3 ⁄16 in. (5 mm) and 3⁄16 in. (5 mm) through 11⁄4 in. (32 mm) thickness ranges]. | Quiery No.3 Is there any problem for showing all material range in a single WPS based on above PQR? Ie, qualified range of materials- P1 Group No. 1 & P1 Group No. 2 in the same WPS. No problem.You can write all material range as much as possible within the P number specified in the WPS Thanks & Regards, (Karthik)

I need your help in the following subject. Design Code – ASME B31.3 Welding Code – ASME BPV SECTION IX I have a PQR for the following material classification as per ASME BPV SEC IX Material – P1 Group No. 1 to P1 Group No. 2 Weld Metal Impact Tested – Yes My query is that, 1. Is there any problem for welding P1 Group No.1 to P1 Group No.1 & P1 Group No.2 to P1 Group No.2 based on above PQR? 2. Can I write separate WPS (with impact test) based on above PQR for, Material – P1 Group No. 1 to P1 Group No. 1 Material – P2 Group No. 2 to P2 Group No. 2 My next query is that, Is there any problem for showing all material range in a single WPS based on above PQR? Ie, qualified range of materials- P1 Group No. 1 & P1 Group No. 2 in the same WPS.
