4. Terms and definitions


 Preliminary Welding Procedure Specification (pWPS) – a reference document to be
used by the welder to complete a welding procedure qualification test piece. Along with
the dimensions, joint configuration, consumable type etc it gives the suggested welding
parameters to be used (i.e. current, voltage, welding speed) based on the responsible
welding coordinator knowledge and/or past experience.

 Welding Procedure Qualification Record (Welding Procedure Approval Record) –


(WPQR/WPAR) – a record comprising all necessary data needed for qualification of
preliminary welding procedure specification.

 Welding Procedure Specification (WPS) – a document that has been qualified. It


provides the required variables of the welding procedure to ensure repeatability during
production welding.

 Weld Plan – a document or drawing also known as "weld map" that is indentifying WPS
and inspection/NDE requirements for each individual weld.

 Welding Book – a document that contains all related WPSs and WPQRs for the given
part. It may contain weld plan.

 Supplier Master Document Register (SMDR) – an agreement between the supplier and
FMC Technologies on what documents the supplier shall submit for review.

 Database Information (DBI) – product description / technical requirements overview.

 Material Selection and Corrosion Protection Philosophy – a document that presents


the overall strategy for the material selection, fabrication, corrosion protection and thermal
insulation related to the deliveries for the given project based on customer and FMC
requirements and agreed clarifications.

Welding documentation flow at supplier

5. Review of single WPS


5.1. General
Supplier includes procedures like WPS / WPQR, Coating Procedures, Heat treatment Procedures
and NDE Procedures in SMDR (see appendix A) and send to FMC for review and approval. The
same procedures can be submitted for different projects. As a general rule, all procedures should
be reviewed in a DR4 form for each Project. In some cases (on standard products) a general

 
approval for all projects can be given if the requirements are the same regardless of project
specific requirements.

Short overview of supplier’s documents related to welding to be found in Table 1.

The submitted, specified WPS shall be reviewed to the following:

1. Product and relevant requirements in DBI (see Appendix B)


Can the WPS be used on the specific weld? - Drawing on the DBI or weld plan (weld
map) listed in the SMDR to be checked. - Ambitious! (Finn)

2. Project requirements (specified in Material Selection and Corrosion Protection


Philosophy).

It is the WPS that will be reviewed; WPQRs are supporting documents and will not get a separate
approval code, but will be referred to in the DR4 form. Technical requirements in standards,
specs and regulations should be fulfilled as far as possible. If this is not possible engineering
judgment shall be used. The criticality of the Product must be considered in such cases. ON
HOLD: Typical welds with high criticality are pressure containing welds, fatigue sensitive welds,
cladding, welds of high load structural components. Other structural welds (e.g. ROV basket)
have lower criticality. This is also reflected in the design class and steel quality level.

 
Review of WPS is documented in DR4 form for material department, each WPS and Project.
Example of DR4 is to be found in Appendix C.

5.2. Approval status codes


Review codes to be used on DR4:

"1" - Accepted with no comments


"2" - Accepted with comments - ON HOLD: to be deleted?
"2x" - Document returned before the customer's final approval / comments. Please hold next
revision of the document until receipt of FMC final comments, or until document is given approval
status code 1.
"3" - Rejected, with comments
"4" - For information only

Comments to use of codes:

Production can start when WPS is in code "1" or "2".

ON HOLD: code 2 to be deleted? Code "2" means minor comments in terms of clarifications
according to spec requirements. Code “2” comments shall always refer to specific requirements
(code or project)!

Code "2x" is an information to supplier that FMC have no comments, but client will also review
the document. Start of production is at supplier’s risk. Some projects do not approve the use of
code "2x". To be checked with project prior to review.

Code "3" means "STOP" and should be used only when the technical content is such that it is not
advisable to fabricate - Finn disagree. In these matters direct communication between FMC
Materials Engineer and supplier is needed to clarify and agree upon alternative and acceptable
solutions. Code “3” comments shall always refer to specific requirements (code or project)!

Finn: if deemed necessary by the reviewer code 3 can be used to ensure implementation of
comments before start of welding.

!! NOTE: under no circumstances can the DR4 review be used in lieu of a deviation /
concession request. In cases where a deviation / concession request has been handled in
the QN system it can be referred to in the DR4

For typical code 2 and 3 see Appendix D.

5.3. Checklist
In general the following information is to be checked while reviewing WPS:

I. WPS content and range of approval

II. WPQR front page content (shall be stamped / signed by an examiner (third party)

III. Extent of destructive and NDE testing and test results: reports attached to WPQR (shall
be stamped / signed by an examiner (third party))

IV. Parent and filler material certificates, PWHT report



 
V. Weld log. ON HOLD: we don’t have requirements for this. If we start asking weld log many
of existing WPSs will be invalid.

5.4. WPS content and range of approval


Review of WPS shall ensure that the WPS essential parameters are covered qualified by the
WPQR. WPS shall provide all the necessary information required to make a weld.

Welding Procedure Specification and WPQRs content shall be prepared in accordance with ISO
15614-1 (-5/ -7/ -11) (see example of WPS in Appendix E) or ASME IX (see example of WPS in
Appendix F).

Requirements for essential variables and acceptance range shall be checked in accordance with
the following standards:

For piping systems: ASME IX / Norsok M-601 and ISO 15614 + customer specs

For structural welds: Norsok M-101 and ISO 15614 or AWS D1.1 + customer specs

ISO 15614, Norsok M-601, Norsok M-101 and AWS D1.1 contain essential and nonessential
variables. ASME IX also defines supplementary essential variables.

Essential variables are conditions in which a change, as described in the specific variables, is
considered to affect the mechanical properties of the joint. Before using a procedure specification
whose essential variables have been revised and fall outside their qualified range, the procedure
specification must be re-qualified.
Supplementary essential variables are conditions in which a change will affect the toughness
properties of the joint, heat-affected zone, or base material. Supplementary essential variables
become additional essential variables in situations where procedure qualifications require
toughness testing. When procedure qualification does not require the addition of toughness
testing, supplementary essential variables are not applicable.
Nonessential variables are conditions in which a change, as described in the specific variables,
is not considered to affect the mechanical properties of the joint. A procedure specification may
be editorially revised to change a nonessential variable to fall outside of its previously listed
range, but does not require requalification of the procedure specification.

Explanation of WPS / WPQR content is given in Appendix G.

Additional requirements are listed in FMC specifications and Customer specifications. References
to these specifications are to be found in Material Selection and Corrosion Protection Philosophy
for the project.

5.5. Extent of testing and test results (reports attached to WPQR)


Extent of testing based on materials, weld type and geometry to be checked. All test reports shall
be attached to WPQR.

Testing includes both non-destructive (NDT) and destructive testing which shall be in accordance
with the requirements of relevant standard and client specs.

Impact test: test temperature shall be in compliance with project minimum design temperature
requirements / spec requirements.

ON HOLD: NDE reports: acceptance criteria (name of reference standard) to be checked.



 
5.6. Parent and filler material certificates, PWHT report
The WPQR / PQR documentation shall include the material certificates for the base and filler
materials applied in the weld qualification test according to Norsok M-101, Norsok M-601. PWHT
report and legible time vs temperature chart shall be included in the WPQR.

Chemical composition, mechanical properties, microstructure (if applicable), ferrite counting (if
applicable), corrosion test (if applicable) shall be checked according to international standards /
FMC material specs / customer specs. Reference code requirement (NORSOK, ASME IX, etc)
shall be stated.

Only material certificates type 3.1 and 3.2 according to BS EN 10204 are acceptable.

5.7. WPS review history

5.7.1. New WPS


New WPS (first time review) shall be checked by 2 Material Engineers (quality check).
Double check will help to avoid mistakes and next reviewers will not need to review WPS
against Norsok / ASME IX / AWS D1.1 requirements, but only to product and project
requirements.

5.7.2. Reuse of WPS


WPS may be used for many projects and therefore receive several DR4’s. If the Project
requirements are different, the WPS can get different approval codes.

Content of DR4 of previous reviewers for given WPS is to be checked prior to issue of a
new DR-4.

5.7.3. FMC approval code disagreement


In cases where a previous approval code is not agreed the review responsible Materials
Engineer must contact the previous reviewer in order to clarify the disagreement.

In cases where previous reviews are made incorrect the consequences on previous PO’s
must be evaluated and, based on criticality, QN shall be issued.
