Question(s) and Reply(ies): Background: A WPS with supporting PQR was written and qualified without impact testing in 1978 to the 1977 Code without addenda on a NPS 2 (EN50) diameter x 0.432 inch (11 mm) wall thickness pipe. The procedure was qualified in 6G position using an E6011 (F-No. 3) electrode on the root pass and completed with two fill passes with E7018 (F-No. 4) electrode. The deposit thickness for the root and fill passes was not recorded on the PQR or specified individually on the WPS.

SC IX; QW-322.1(a) - Expiration of Qualification 05/29/2014 14-255

Question(s) and Reply(ies): Background: A welder/welding operator is required to weld with a process within a six month period, in order to maintain qualification to use that process. A welder/welding operator takes a performance qualification test using a process for which the welder is already qualified (e.g. SMAW), but with different essential variables (e.g. different F-number, progression, etc.). During the performance of the test, the organization responsible for supervising and controlling the test, visually examines the weld and determines that it meets the visual acceptance criteria of QW-194. Subsequently, the test coupon is subjected to volumetric NDE or mechanical testing, and fails to meet the acceptance criteria. Question: May a failed performance qualification test, utilizing a process for which the welder/welding operator is currently qualified, satisfy the requirements of QW-322.1(a) for maintaining continuity?

coupon. P-No. 5 has since been deleted, and CrMo materials have been reassigned to P-Nos. 5A, 5B, and 5C, with SA-213-T9 being assigned to P-No. 5B. It can be demonstrated that SA-213-T9 is now designated as a P-No. 5B material.

Question (1): QW-100.3 allows the continued use of welding procedures qualified under previous editions and addenda of the Code without revision to include any variables required by later editions and addenda. Is it the intent of QW-100.3 to allow the use of this WPS to join P-No. 5A, P-No. 5B, or P-No. 5C materials without requalification when toughness is not a consideration?

Reply (1): No. QW-I00.3 applies when later Code editions and addenda have added new variables for a given welding process. While this WPS can be shown to be qualified for welding P-No. 5B materials to each other, it is intended that the WPS be editorially revised to show applicability of the WPS to the originally qualified materials under the material grouping assignment found in the applicable edition and addenda of Section IX. See QW-420.1 and QW-200.2(c). Question (2): Is it the intent of Section IX that the WPS described above is acceptable for joining all materials previously assigned P-No. 5?

Reply (2): No. Based upon the original PQR, the WPS is qualified only for joining materials assigned to P-No. 5B under the current Section IX rules. See QW-403.13. Standard Designation: Edition/Addenda:

An alternate WPS is proposed for depositing the weld metal overlay to increase the overlay thickness or perform the repairs.

QW-200.1(b)

Record Number:

11-1476

Date Issued:


09/13/2012 IX-13-03

Question(s) and Reply(ies): Background: QW-200.1(b) says: "The completed WPS shall describe all of the essential, nonessential, and, when required, supplementary essential variables for each welding process used in the WPS."

Question (1): If a WPS is written and qualified for welding P-No.1 material to itself, is it necessary to specifically mention on the WPS or on the PQR anything regarding QW-410.64, which addresses the use of thermal processes for cutting or backgouging when welding on P-No.11A and P-No.11B materials?


2016/5/4

页码，37/40

Reply (1): No. The fact that the WPS and PQR are for welding on P-No.1 materials precludes the need to specifically describe the use of thermal cutting or backgouging for P-No.11A or P-No. 11B materials on either the WPS or the PQR. Question (2): If a WPS specifies the use of ER70S-6 filler metal, is it necessary to specifically mention in the WPS anything regarding QW404.23, which addresses filler metal product form by specifying that the filler metal has to be solid?

Reply (2): No. The designation ER70S-6 specifies that the filler metal be solid wire, and that is sufficient for describing the variable QW-404.23.

Question (3): If a WPS is written and qualified for welding P-No. SA material to itself, is it necessary to specifically mention on a WPS or on the PQRs for submerged arc welding anything regarding QW-404.34 that addresses, when welding on P-No.l materials, the use of active or neutral flux?

Reply (3): No. The use of active or neutral fluxes only needs to be specified on the WPS and documented on the PQR when the base metal is P-No.1. Standard Designation: Edition/Addenda:

QW-410.9

Record Number:

12-1529

Date Issued:


06/10/2013 IX-13-12

Question(s) and Reply(ies): Background: Impact testing of welding procedure qualifications is required by the Construction Code and QW-410.9 applies to the welding process used as a supplementary essential variable. QW-410.9 requires requalification for a change from multipass per side to single pass per side. Per QW/QB-492 Definitions, a pass can result in a weld bead or a layer. Question (1): Does QW-410.9 regard multiple layer welds as multipass welds, so that a change from multiple layers per side to a single layer per side requires a requalification? Reply (1): Yes, when the single layer is made in a single pass.

Question (2): Does QW-410.9 regard multiple beads in a single layer (as shown in beads 3, 4, 5, and 6 of Figure QW/QB-492.1) as “multipass”? Reply (2): Yes.

Question (3): A Welding Procedure Specification is qualified with multiple layers per side. Can this WPS be used to deposit multiple beads in a single
