Question (1): A manufacturer's WPS to weld P-No. 4 to P-No. 4 metals specifies a minimum preheat temperature of 150°C (302°F) with PWHT at 593°C: (1099°F) to 650°C (1202°F). The supporting PQR to this WPS shows PWHT was performed at 700° C (1292°F) to 720°C (1328°F). Does the PWHT of the PQR support this WPS? Reply (1): Yes. Question (2): When qualifying a WPS, a welded tensile test specimen of SA-106 Gr. A (48,000 psi UTS) failed at 45,600 psi, which is 95% of the UTS of the pipe, the UTS of the failed specimen conforms to QW-153(d). May this WPS be used to weld P-No. 1 to P-No. 1 metals using 70,000 psi filler metal which is other than the A-Number and F-Number shown on the PQR? Reply (2): No. See QW-404.4.

Standard Designation: BPV Section IXEdition/Addenda:Para./Fig./Table No:Subject Description: Section IX, Use of Consumable InsertsDate Issued: 07/02/1982Record Number: BC82-245Interpretation Number : IX-83-06Question(s) and Reply(ies): Question (1): A consumable insert is fused between two test coupons using

GTAW process and no filler wire, the remaining passes deposited by the SMAW process. For welder qualification, is the welder qualified to make a field weld with the GTAW process and using bare wire (E 70S2) over the consumable insert? Reply (1): No. Question (2): If the GTAW process has qualified the welder to make such a deposit over the consumable insert, although he has not made a deposit in the qualification test, then would the welder's qualification of the GTAW process allow the welder to make a deposit with the GTAW process and the use of bare filler wire without the consumable insert having been preplaced? Reply (2): No.

PWHT of 1400F. Can this PQR be used in accordance with QW-403.11 to support a WPS for P-No. 5 to P-No. 1 materials with a PWHT to be conducted at 1400°F? Reply (1): No. PWHT of P-No. 1 material at 1400F is between the upper and lower transformation temperatures. QW-407.1(a)(5) requires separate qualification for this condition. Question (2): For the PQR and WPS described in Question (1), is the maximum base metal thickness of the WPS limited to 1.1 times the base metal thickness of the PQR per QW-407.4 since the critical temperature of the P-No. 1 material has been exceeded? Reply (2): The critical temperature range of the P-No. 1 material has not been exceeded; therefore, QW-407.4 does not apply.

Standard Designation: BPV Section IXEdition/Addenda:Para./Fig./Table No:Subject Description: Section IX, QW-451.1Date Issued: 09/19/1983Record Number: BC83-395Interpretation Number : IX-83-81Question(s) and Reply(ies): Question (1): In the Winter 1982 Addenda to Section IX, the minimum

values for "Thickness t of Deposited Weld Metal Qualified" in QW-451.1 were deleted. Does this mean there are no minimum thickness qualifications for deposited weld metal? Reply (1): When determining the minimum thickness qualifications per QW-451.1, Notes (1) and (2) must also be considered. In those cases where the further limitation of these Notes does not apply, there is no limit on the minimum thickness qualification. Question (2): If impact tests are required for an SMAW procedure qualification, may the thickness limitations of Note (1) of QW-451.1 be overridden in determining the minimum deposited weld metal thickness qualification?
