Subject Description: QW-201, Manufacturer's or Contractor's Responsibility




Question(s) and Reply(ies): Background: A large majority of fabrication contracted by a design

Company A is performed by Manufacturers B and C. Each company is

independent in ownership from the other two. Companies A, B, and C havedeveloped a Welding Coalition. The top management of all three companies

has executed an Agreement and Commitment protocol consenting to the

establishment of this Welding Coalition. The Welding Coalition controls all

weld procedures developed for use on Company A contracts by Companies

B and C under one designated program. The Coalition does not control

production welding at either of the manufacturing companies. Weld

procedure qualifications performed by Company C are controlled by

Company A's Quality Program. Weld procedure qualifications performed

by Company B are controlled by Company B's Quality Program that has

been approved by Company A. Company C is on Company B's ApprovedVendors List.

Question: Is it permissible to consider the Welding Coalition as "the

organization which has responsible operational control of production of the

weldments to be made in accordance with this Code" such that Company B

may use weld procedures qualified by Company C and vise versa?

Reply: No.

machine or automatic GTAW hard-facing process, with or without

oscillation, may be used to qualify a WPS for a manual, or a semiautomatic

GTAW hard-facing process, with or without weave?

Reply: Yes. Note that recent actions by Section IX have defined oscillation

as applicable to machine and automatic processes and wave as applicable tomanual and semiautomatic processes.

qualification continuity when a new owner acquires a manufacturer or

contractor. If welder performance qualification continuity is to be

maintained by the new owner, the Quality Control System/Quality

Assurance Program should reflect to the source of the welder performance

qualification records as being from the former manufacturer or contractor.

Question(s) and Reply(ies): Background: ASME Section IX, Addenda 2000, revised table QW-452.1

reducing the coupon size from 3/4 in. to 1/2 in. to qualify the welder for

"Maximum to be welded" when welding a minimum of three layers.

Question (1): A welder qualified prior to Addenda 2000 and has remained

qualified since his original test. His original test coupon consisted of at leastthree weld layers and greater than 1/2 in. but less than 3/4 in. deposited

weld metal. May the qualification recorded be revised from "2t" to "Max. to

qualification has lapsed due to not welding with the original weld process

for greater than 6 months. His original test coupon consisted of at least three

layers and greater than 1/2 in. but less than 3/4 in. deposited weld metal. His

renewal restores his original qualifications in accordance with QW-322.2

assembler, or installer "be responsible for conducting tests to qualify the

performance of welders which his organization employs in construction ofweldments built in accordance with the Code." It also requires that the

manufacturer, contractor, assembler, or installer provide supervision and

control over welders while they are welding test coupons for performance

qualification.

Question (1): An employee of a contractor provides supervision and control

over a welder during welding of a test coupon, but that welder is not an

employee of the contractor at the time of the test. Is it required that the

welder be an employee of that contractor at the time of qualification

qualified separately per QW-404.37?

Reply (2): Yes.

Question (3): If the Ni-Cr-Fe alloy strip filler metal meets the chemicalcomposition requirements of Code Case 2143-1 and was produced to the

requirements of SFA-5.14, except for the chemical analysis, may the filler

metal be classified as F-43 for procedure and performance qualification?

Reply (3): No.

Question (4): If the Ni-Cr-Fe alloy strip filler metal is not classified in an

SFA specification, and is not covered in Code Case 2142-1 or 2143-1, is it

Background: In all cases described below, the manufacturers develop and

follow WPSs and PQRs based on the test coupons welded. The minimum

buttering thickness in all cases will be greater than 3/I6 in.

Question (1): Manufacturer A qualifies a WPS by buttering the ends of the

test coupons, which are the same material. The buttered ends are heat

treated, then the weld is completed using the same filler metal as was used

for the buttering. Manufacturer B welds a groove weld test coupon of thesame base metal using the same process, filler metal and other essential

variables as manufacturer A. That test coupon is heat treated in the same

manner as the heat treatment used for the buttering by manufacturer A. May

manufacturer A weld parts that were buttered by manufacturer B?

Reply (I): Yes.

Question (2): Manufacturer C welds a groove weld test coupon using the

same base metal, process, filler metal, and other essential variables as

manufacturer A. That test coupon is heat treated in the same manner as the

heat treatment used for the buttering by manufacturer A. May manufacturer

A weld parts that were buttered by manufacturer C?

Reply (2): Yes.

Question (3): Manufacturer A receives parts that have been buttered by both

manufacturers B and C. May the parts buttered by manufacturer B be

welded by manufacturer A to parts buttered by manufacturer C?

Reply (3): Yes.

Question (4): Manufacturer D receives parts that have been buttered by

manufacturers A, B, and C. May manufacturer D weld the buttered parts

together using a buttered groove weld test coupons qualified using the same

base metal, process, filler metal, and other essential variables as

manufacturer A?

Reply (4): Yes.

Question (5): Manufacturer D receives parts that have been buttered by

manufacturers A, B, and C. May manufacturer D weld the buttered parts

together using a groove weld test coupon qualified in accordance with QW-

283.4(b) using the same process, filler metal, and other essential variables

that manufacturer A used to join the buttered parts (i.e., the as-welded

portion of the test) using a base metal that nominally matches the chemical

analysis of the buttering used by manufacturer A, B, or C?

Reply (5): Yes.

Question (6): Manufacturer E welds a groove weld test coupon of another

base metal using the same filler metal as manufacturer A. That test coupon

is heat treated and tested in accordance with QW-202.2(a). May

manufacturer F, who has welded a test coupon in accordance with QW-

283.4(b), join parts buttered by manufacturer E?

Question(s) and Reply(ies): Background: For welder's performance qualification, a multiple layer

groove weld is made on a single test coupon using one welder for first layerand another welder for the second.

Question: QW-301.4 requires a record of welder performance qualification.

May a single form be used to record the essential variables, the type of test

and test results, and the ranges qualified in accordance with QW-452 for

Subject Description: QW-401.3, Supplemental Essential Variable (Procedure)




Question(s) and Reply(ies): Background: A company has qualified a PQR to satisfy all testing

requirements other than notch toughness for welding P1 Group 2 to P1

Group 2 by the SAW process. Another test coupon is subsequently prepared

using the WPS written on the original PQR and an additional PQR is then

qualified with only testing for notch toughness, as allowed by the Code, to

supplement the original PQR for welding with impact requirements.

However, the preheat value (an essential variable) used to qualify the

original PQR was 150°F. The preheat temperature was less than 150°F.

Question: May the supplemental PQR with reduced preheat be used with

the original PQR to support a WPS for notch toughness application?

were previously qualified with an electrode classified as F4, also qualified

to use this unclassified electrode that conforms to the deposit chemistry ofEXXXX-G, in Table 2 of SFA 5.5 (within the other limitations of QW-

350)?

Reply: No.

Question(s) and Reply(ies): Question: Are all-encompassing terms acceptable when addressing

nonessential variables in a WPS (e.g., for backing, "with or without," for

root spacing, "unlimited")?

Reply: Section IX does not specify how nonessential variables are to be

addressed; however, the terms used must provide direction to the

welder/welding operator for making production welds to Code

requirements.
