AWS A5.30/A5.30M:2007
Statement on the Use of American Welding Society Standards
All standards (codes, specifications, recommended practices, methods, classifications, and guides) of the American
Welding Society (AWS) are voluntary consensus standards that have been developed in accordance with the rules of the
American National Standards Institute (ANSI). When AWS American National Standards are either incorporated in, or
made part of, documents that are included in federal or state laws and regulations, or the regulations of other governmental bodies, their provisions carry the full legal authority of the statute. In such cases, any changes in those AWS
standards must be approved by the governmental body having statutory jurisdiction before they can become a part of
those laws and regulations. In all cases, these standards carry the full legal authority of the contract or other document
that invokes the AWS standards. Where this contractual relationship exists, changes in or deviations from requirements
of an AWS standard must be by agreement between the contracting parties.
AWS American National Standards are developed through a consensus standards development process that brings
together volunteers representing varied viewpoints and interests to achieve consensus. While AWS administers the process
and establishes rules to promote fairness in the development of consensus, it does not independently test, evaluate, or
verify the accuracy of any information or the soundness of any judgments contained in its standards.
AWS disclaims liability for any injury to persons or to property, or other damages of any nature whatsoever, whether
special, indirect, consequential or compensatory, directly or indirectly resulting from the publication, use of, or reliance
on this standard. AWS also makes no guaranty or warranty as to the accuracy or completeness of any information
published herein.
In issuing and making this standard available, AWS is not undertaking to render professional or other services for or on
behalf of any person or entity. Nor is AWS undertaking to perform any duty owed by any person or entity to someone
else. Anyone using these documents should rely on his or her own independent judgment or, as appropriate, seek the
advice of a competent professional in determining the exercise of reasonable care in any given circumstances.
This standard may be superseded by the issuance of new editions. Users should ensure that they have the latest edition.
Publication of this standard does not authorize infringement of any patent or trade name. Users of this standard accept
any and all liabilities for infringement of any patent or trade name items. AWS disclaims liability for the infringement of
any patent or product trade name resulting from the use of this standard.
Finally, AWS does not monitor, police, or enforce compliance with this standard, nor does it have the power to do so.
On occasion, text, tables, or figures are printed incorrectly, constituting errata. Such errata, when discovered, are posted
on the AWS web page (www.aws.org).
Official interpretations of any of the technical requirements of this standard may only be obtained by sending a request,
in writing, to the Managing Director, Technical Services Division, American Welding Society, 550 N.W. LeJeune Road,
Miami, FL 33126 (see Annex B). With regard to technical inquiries made concerning AWS standards, oral opinions
on AWS standards may be rendered. However, such opinions represent only the personal opinions of the particular
individuals giving them. These individuals do not speak on behalf of AWS, nor do these oral opinions constitute official
or unofficial opinions or interpretations of AWS. In addition, oral opinions are informal and should not be used as a
substitute for an official interpretation.
This standard is subject to revision at any time by the AWS A5 Committee on Filler Metals and Allied Materials. It must
be reviewed every five years, and if not revised, it must be either reaffirmed or withdrawn. Comments (recommendations, additions, or deletions) and any pertinent data that may be of use in improving this standard are required
and should be addressed to AWS Headquarters. Such comments will receive careful consideration by the AWS A5
Committee on Filler Metals and Allied Materials and the author of the comments will be informed of the Committee’s
response to the comments. Guests are invited to attend all meetings of the AWS A5 Committee on Filler Metals and
Allied Materials to express their comments verbally. Procedures for appeal of an adverse decision concerning all such
comments are provided in the Rules of Operation of the Technical Activities Committee. A copy of these Rules can be
obtained from the American Welding Society, 550 N.W. LeJeune Road, Miami, FL 33126.

AWS A5.30/A5.30M:2007
Foreword
This foreword is not part of AWS A5.30/A5.30M:2007, Specification for
Consumable Inserts, but is included for informational purposes only.
This document is the first of the A5.30 specifications which makes use of both U.S. Customary Units and the International System of Units (SI). The measurements are not exact equivalents, therefore each system must be used independently of the other, without combining values in any way. In selecting rational metric units, the Metric Practice Guide
for the Welding Industry (AWS A1.1) is used where suitable. Tables and figures make use of both U.S. Customary and
SI Units, which, with the application of the specified tolerances, provides for interchangeability of products in both the
U.S. Customary and SI Units.
The current document is the third revision of the AWS document first issued in 1979. Its evolution took place as follows:
A5.30-79
Specification for Consumable Inserts
A5.30-97
Specification for Consumable Inserts
Specific topics include composition, style, profiles, dimensional tolerances, packaging, and package marking. Annex A
suggests general areas of application.

Comments and suggestions for the improvement of this standard are welcome. They should be sent to the Secretary,
AWS A5 Committee on Filler Metals and Allied Materials, American Welding Society, 550 N.W. LeJeune Road,

AWS A5.30/A5.30M:2007
Specification for Consumable Inserts
1. Scope
this AWS standard. For dated references, subsequent
amendments to, or revisions of, any of these publications
do not apply. However parties to agreement based on this
AWS standard are encouraged to investigate the possibility of applying the most recent editions of the documents
shown below. For undated references, the latest edition
of the standard referred to applies.
1.1 This specification prescribes requirements for the
classification of plain carbon steel, chromium-molybdenum
low alloy steel, stainless steel, nickel alloy, and coppernickel alloy consumable inserts1 for use in conjunction
with the gas tungsten arc welding process. These inserts
also may be used with any other welding process for
which they are found suitable. Included are packaging
and testing requirements.
2.1 The following ANSI and AWS standards2 are referenced in the normative clauses of this document:
1.2 Safety and health issues and concerns are beyond the
scope of this standard and, therefore, are not fully
addressed herein. Some safety and health information
can be found in the Informative annex Clauses A5 and
A10. Safety and health information is available from
other sources, including, but not limited to ANSI Z49.1,
Safety in Welding, Cutting, and Allied Processes, and
applicable federal and state regulations.
1. AWS A5.01, Filler Metal Procurement Guidelines
2. ANSI Z49.1, Safety in Welding, Cutting, and
Allied Processes
2.2 The following ASTM standards3 are referenced in the
normative clauses of this document:
1. ASTM DS-56 (or SAE HS-1086), Metals & Alloys
in the Unified Numbering System
1.3 This specification makes use of both U.S. Customary
Units and the International System of Units (SI). The
measurements are not exact equivalents, therefore, each
system must be used independently of the other without
combining in any way when referring to material properties. The specification with the designation A5.30 uses
U.S. Customary Units. The specification A5.30M uses SI
Units. The latter are shown within brackets [ ] or in appropriate columns in tables. Standard dimensions based on
either system may be used for sizing of consumable
inserts under A5.30 and A5.30M.

3. Classification4
5. Certification
3.1 The consumable inserts covered by this A5.30/
A5.30M specification are classified using a system that
is independent of U.S. Customary Units and the International System of Units (SI). Classification is according
to chemical composition of the insert material as specified in Tables 1, 2, 3, and 4. Inserts are also classified by
their shape as specified in 11.1 to 11.6, and in Figure 1.
By affixing the AWS specification and classification
designations to the packaging, or the classification to the
product, the manufacturer certifies that the product meets
the requirements of this specification.6
6. Rounding-Off Procedure
3.2 Consumable inserts classified under one classification shall not be classified under any other classification
of this specification.
For the purpose of determining conformance with this
specification, an observed or calculated value shall be
rounded to the “nearest unit” in the last right-hand place
of figures used in expressing the limiting value in accordance with the rounding-off method given in ASTM
E 29.
4. Acceptance
Acceptance5 of the consumable inserts shall be in accordance with the provisions of AWS A5.01.
7. Summary of Tests
Chemical analysis of the consumable insert material, or
the stock from which it is made, is the only test required
for classification of a product under this specification.
4
See Table A.1 for comparable classifications of bare wire
filler metal in AWS specifications and for consumable inserts
in the Military Specification.
5 See A3 (in Annex A) for further information concerning
acceptance and testing of material shipped, and AWS A5.01.
6 See A4 (in Annex A) for further information concerning certification and the testing called for to meet this requirement.

8. Retest
In the event that, during preparation or after completion of any test, it is clearly determined that prescribed or proper procedures were not followed in
preparing the test specimen(s), or in conducting the
tests, the test shall be considered invalid, without
regard to whether the test was actually completed, or
whether test results met, or failed to meet, the requirement. That test shall be repeated, following proper
prescribed procedures. In this case, the requirement
for doubling the number of test specimens does not
apply.
If the results of any test fail to meet the requirement, that
test shall be repeated twice. The results of both retests
shall meet the requirement. Samples for retest may be
taken from the original test sample or from a new test
sample. A retest need be only for those specific elements
that failed to meet the test requirement. If the results of
one or both retests fail to meet the requirement, the material under test shall be considered as not meeting the
requirements of this specification for that classification.

Class 3, Style D insert rings are normally furnished to match nominal internal diameter of the pipe as shown in Table 6. For Class 3, Style D insert
rings required for use with specially I.D. machined pipe end joint preparation, the dimensions are determined as follows:
. Ring ID = pipe ID minus 0.094 in [2.38 mm]
Ring OD = ring ID + 0.375 in [9.53 mm]
b Schedule number followed by “S” applies to Group C Types.

Annex A (Informative)
Guide to AWS Specification for Consumable Inserts
This annex is not part of AWS A5.30/A5.30M:2007, Specification for
Consumable Inserts, but is included for informational purposes only.
A1. Introduction
In particular, the request needs to include:
The purpose of this guide is to correlate the filler metal
classifications with their intended applications so that
this specification may be used effectively.
a. All classification requirements as given for existing classifications, such as, chemical composition
ranges, and available sizes, classes, and styles.
A2. Classification System
b. Any conditions for conducting the tests used to
demonstrate that the product meets the classification
requirements. (It would be sufficient, for example, to
state that welding conditions are the same as for other
classifications.)
A2.1 The classification system used in this specification
follows, as closely as possible, the standard pattern used
in other AWS filler metal specifications. The inherent
nature of the products being classified has, however,
necessitated specific changes that more precisely classify
the product. As an example, consider IN308. The prefix
“IN” designates a consumable insert. The numbers 308
designate the chemical composition.
c. Information on Description and Intended Use,
which parallels that for existing classifications, for that
clause of Annex A.
The request for a new classification without the above
information will be considered incomplete. The Secretary will return the request for further information.
A2.2 While consumable inserts are classified on the
basis of their chemical composition, the cross-sectional
configuration, designated by class number (Figure 1),
size (Tables 6, 7, and 8), and style (Clause 11), must also
be specified when ordering.
3. The request should be sent to the Secretary of the
Committee on Filler Metals and Allied Materials at AWS
Headquarters. Upon receipt of the request, the Secretary
will:
a. Assign an identifying number to the request.
This number will include the date the request was
received.
A2.3 Request for Filler Metal Classification
1. When a filler metal cannot be classified according
to a standard classification, the manufacturer may
request that a classification be established for that filler
metal. The manufacturer may do this by following the
procedure given here.
b. Confirm receipt of the request and give the
identification number to the person who made the
request.
c. Send a copy of the request to the Chair of the
A5 Committee on Filler Metals and Allied Materials, and
the Chair of the particular Subcommittee involved.
2. A request to establish a new filler metal classification must be a written request, and it needs to provide
sufficient detail to permit the A5 Committee on Filler
Metals and Allied Materials or the Subcommittee to
determine whether the new classification or the modification of an existing classification is more appropriate,
and whether either is necessary to satisfy the need.
d. File the original request.
e. Add the request to the log of outstanding
requests.

Metals and Allied Materials meeting. Any other publication
of requests that have been completed will be at the option of
the American Welding Society, as deemed appropriate.
A2.3.4 All necessary action on each request will be
completed as soon as possible. If more than 12 months
lapse, the Secretary shall inform the requester of the
status of the request, with copies to the Chair of the A5
Committee and Subcommittee. Requests still outstanding after 18 months shall be considered not to have been
answered in a “timely manner” and the Secretary shall
report these to the Chair of the A5 Committee on Filler
Metals and Allied Materials for action.
A2.4 An international system for designating welding
filler metals developed by the International Institute of
Welding (IIW) is being adopted in many ISO specifications. Table A.1 shows the proposed designations for
consumable inserts. To understand the proposed international designation system, one is referred to the
tables and annex of the AWS publication document
IFS:2002, International Index of Welding Filler Metal
Classifications.
A2.3.5 The Secretary shall include a copy of the log of
all requests pending and those completed during the preceding year with the agenda for each Committee on Filler

AWS Classification

AWS A5.30/A5.30M:2007
A3. Acceptance
4. The proximity of the welder or welding operator to
the fumes, as these fumes issue from the welding zone,
and to the gases and dust in the space in which they are
working
Acceptance of all welding materials classified under this
specification is in accordance with AWS A5.01, Filler
Metal Procurement Guidelines, as the specification
states. Any testing a purchaser requires of the supplier,
for material shipped in accordance with this specification, needs to be clearly stated in the purchase order,
according to the provisions of AWS A5.01. In the
absence of any such statement in the purchase order, the
supplier may ship the material with whatever testing is
normally conducted on material of that classification, as
specified in Schedule F, Table 1, of AWS A5.01. Testing
in accordance with any other schedule in that Table must
be specifically required by the purchase order. In such
cases, acceptance of the material shipped will be in
accordance with those requirements.
5. The ventilation provided to the space in which the
welding is done
A5.2 American National Standard ANSI Z49.1, Safety in
Welding, Cutting, and Allied Processes (published by the
American Welding Society), discusses the ventilation
that is required during welding and should be referred to
for details. Attention is drawn particularly to the clause
on Ventilation in that document.
A6. Description of the Process
A6.1 General. Consumable inserts are used for root pass
welding from one side where consistent, high quality
welds are required with minimum repairs, or rejects, and
where welding conditions may be less than optimum,
such as confined space for welding or the necessity for
maximum assurance against weld cracks, etc. Consumable inserts are most often used in pipe joints,
and frequently used in pressure vessel and structural
applications.
A4. Certification
The act of placing the AWS specification and classification designations on the packaging enclosing the product, or the classification on the product itself, constitutes
the supplier’s (manufacturer’s) certification that the product meets all of the requirements of the specification.
The only testing requirement implicit in this certification
is that the manufacturer has actually conducted the tests
required by the specification on material that is representative of that being shipped and that that material met the
requirements of the specification. Representative material, in this case, is consumable insert material from any
production run of that classification. “Certification” is
not to be construed to mean that tests of any kind were
necessarily conducted on samples of the specific material
shipped. Tests on such material may, or may not, have
been conducted. The basis for the “certification”
required by the specification is the classification test of
“representative material” cited above, and the “Manufacturer’s Quality Assurance Program” in AWS A5.01.
--`,```,```,,```,,,``,,``,,,,,,`-`-`,,`,,`,`,,`---
A6.2 Purging. To provide welded piping systems with
the integrity required by some piping codes, the weld
joint must be a full penetration joint with weld metal of
consistently good quality. One method of obtaining this
high level of quality is the use of preplaced consumable
inserts in conjunction with a specific joint configuration
together with a suitable protective gas back purge. The
gas tungsten arc welding process, either manual or automatic, generally is used to consume or fuse the consumable insert. This method is particularly adaptable to
conditions encountered in pipe welding but also may be
applied to flat plate type joints. The main consideration
is that a full penetration groove weld is required when
the accessibility is limited to one side or when the
reverse side of the joints is inaccessible for welding. In
order to obtain a suitably smooth, uniform under side
weld surface without crevices or oxidation, a purge may
be established using a suitable protective gas. Since the
second and third passes in the joint may take the previously deposited consumable insert root pass above the
oxidizing temperature of the base and filler metal, it may
be necessary to maintain the purge until three layers or at
least 3/16 in [5 mm] root thickness is obtained.
A5. Ventilation during Welding
A5.1 Five major factors govern the quantity of fumes to
which welders and welding operators are exposed during
welding. They are as follows:
1. Dimensions of the space in which welding is done
(with special regard to the height of the ceiling)
2. Number of welders and welding operators working
in that space
A6.3 Ferrite Content. For austenitic stainless steel consumable inserts, the purchaser should specify in the purchase order the applicable limits of the Ferrite Number
(FN) required in the consumable inserts. In general, the
3. Rate of evolution of fumes, gases, or dust, according to the materials and processes involved

AWS A5.30/A5.30M:2007
being welded. As much as 40%, or even 50%, of the
weld pass may consist of metal fused from the adjacent
edges at the root of a welded pipe joint. This amount of
dilution may have a significant effect on the properties of
the weld, as for example in estimating ferrite content in
stainless steels or soundness in nickel alloy welds. The
composition of the consumable insert may thus require
somewhat higher levels of certain elements than for other
weld filler metals to compensate for such dilution
effects. An example of the dilution effect in the ferrite
number of stainless steel weld pass is shown in Figure A.2.
limits applied to the matching filler metal type being
used in the joint are recommended for the consumable
insert. Ferrite should be measured on a weld metal pad
by means of a suitable instrument that has been calibrated in accordance with AWS A4.2, Standard Procedures for Calibrating Magnetic Instruments to Measure
the Delta Ferrite Content of Austenitic Stainless and
Duplex Ferritic-Austenitic Stainless Steel Weld Metal.
Alternately, the Ferrite Number can be estimated from
the chemical composition of the insert using the constitution diagrams prepared through the efforts of the Welding Research Council, shown in Figure A.1.
A6.4 Joint Configuration. The joint end preparation
configuration should be compatible with the shape of the
consumable insert used in order to obtain consistent high
quality, particularly under field welding conditions.
A7. Ordering Information
When ordering inserts, the following information needs
to be included:
For all shape configurations, the butt gap in the insert
(fitted, ready for tack welding) should not exceed 1/16 in
[1.6 mm].
1. Title, number, and date of this specification
2. Classification, shape, style and size, including pipe
schedule or pipe inside diameter
A6.5 Dilution. The weld metal composition will be significantly affected by the composition of the parent metal
3. Required Ferrite Number (stainless steel types).

--`,```,```,,```,,,``,,``,,,,,,`-`-`,,`,,`,`,,`---
By the use of the FERRITEPREDICTOR™ software (see Note 1) one can plot the compositions of base metals and filler
metals to arrive at a prediction of the weld metal ferrite in various situations. This graph shows an enlarged section of the
WRC-1992 Diagram. If the two Type 347 base metals at the extreme composition limits of the specifications, 347-SS-1 in
the ferrite solidification mode region, and 347-SS-2 in the austenite solidification mode region, are welded with equal fusion
of both base metals without filler metal, the ferrite would be predicted at position “1.” If filler metal 347-FM is deposited as a
bead-on-plate with 30% dilution on base metal, 347-SS-2, the ferrite prediction would be that found at position “2,” less than
2 FN. The same filler metal with the same dilution on base metal 347-SS-1 will produce a weld metal with 9 FN as shown at
position “3.” A weld joining the two base metals with equal fusion of each side and using the 347-FM filler metal with 30%
dilution will have a Ferrite Number of 4, shown at position “4.” This illustrates the importance of knowing not only the
composition of the filler metal, but also that of the base metals being welded when estimating the ferrite which may be
found in the weld metal.

A8. Description and Intended Use of
Consumable Inserts
cations. However, a fusibility test may be specified. Figure A.3 illustrates a typical Fusibility test joint in plate.
This test is applied with tungsten arc torch on the face
side of a flat plate whose back is enclosed so as to retain
the purging gas at atmospheric pressure. By testing in the
vertical up position for half the joint and in the flat position for the second half, the test evaluates the suitability
of the insert to perform suitably in a pipe welded in the
5G (horizontal fixed) position. A visual examination of
the weld on both the front and back sides gives assurance
that the insert will become completely fused and provide
suitable weld contour in accordance with Note 5 of
Figure A.3.
A8.1 Cross-Sectional Configurations. The selection of
the shape of an insert (designated “class”), is largely determined by the preference of the engineer and operator for a
given application. The Class 1 shape has been preferred
for many highly critical weld joints especially in nuclear
piping and in high temperature, high pressure piping
installation. The Class 2 shape is suitable where the pipe
alignment is less critical. The Class 3 shape requires compositions normally found in rod or wire forms for welding
filler metals, and thus requires flattering and forming into
solid rings to the required shapes and sizes. The Class 4
shape is suitable mainly for V-groove weld preparations.
The Class 5 shape, like that of Class 3, is flattened from
rod or wire comparable to bare welding filler metal compositions, but is not formed into solid rings, allowing the
operator to size the ring to that of the pipe diameters.
A9.2 Applications. A complete description of how to
use consumable inserts is beyond the scope of this document. For further information, see AWS D10.4, Recommended Practices for Welding Austenitic Chromium
Nickel Stainless Steel Piping and Tubing, and AWS
D10.11, Recommended Practices for Root Pass Welding
and Gas Purging. Standard Welding Procedures making
use of consumable inserts are set forth in AWS B2.1-1210 for carbon steel pipe joints, B2.1-8-215 and B2.1-8216 for austenitic stainless steel pipe joints.

A8.2 Style. Class 1, 2, and 5 are available in continuous
lengths (Style A) from which the user can fit to the
desired joint configuration or to form rings to the desired
size. Preformed rings can be supplied either with an overlap (Style B) to allow for contraction or expansion to the
exact pipe size as needed, or for butted rings (Style C) to
fit the specified pipe or tube inside diameter. Class 3 solid
rings (Style D and E) are supplied to match the dimensions of standard pipe sizes as shown in Tables 6 and 7.
A10. General Safety Considerations
A8.3 Compositions. As shown in Tables 1 to 4, four
groups of compositions are standardized, Group A for
the three carbon steel applications, differing in carbon
manganese and silicon; Group B for the types most
commonly used chromium-molybdenum steel pipes and
tubes, differing principally in chromium and molybdenum; Group C for the commonly employed stainless
steel pipe and tube joints; and Group E for the nonferrous nickel and nickel copper alloys.
A10.1 Safety and health issues and concerns are beyond
the scope of this standard and, therefore, are not fully
addressed herein. Some safety and health information

Annex B (Informative)
Guidelines for the Preparation of Technical Inquiries
This annex is not part of AWS A5.30/A5.30M:2007, Specification for
Consumable Inserts, but is included for informational purposes only.
B1. Introduction
along with the edition of the standard that contains the
provision(s) the inquirer is addressing.
--`,```,```,,```,,,``,,``,,,,,,`-`-`,,`,,`,`,,`---
The American Welding Society (AWS) Board of Directors
has adopted a policy whereby all official interpretations
of AWS standards are handled in a formal manner.
Under this policy, all interpretations are made by the
committee that is responsible for the standard. Official
communication concerning an interpretation is directed
through the AWS staff member who works with that
committee. The policy requires that all requests for an
interpretation be submitted in writing. Such requests will
be handled as expeditiously as possible, but due to the
complexity of the work and the procedures that must be
followed, some interpretations may require considerable
time.
B2.2 Purpose of the Inquiry. The purpose of the inquiry
shall be stated in this portion of the inquiry. The purpose
can be to obtain an interpretation of a standard’s requirement or to request the revision of a particular provision
in the standard.
B2.3 Content of the Inquiry. The inquiry should be
concise, yet complete, to enable the committee to understand the point of the inquiry. Sketches should be used
whenever appropriate, and all paragraphs, figures, and
tables (or annex) that bear on the inquiry shall be cited. If
the point of the inquiry is to obtain a revision of the standard, the inquiry shall provide technical justification for
that revision.
B2. Procedure
B2.4 Proposed Reply. The inquirer should, as a
proposed reply, state an interpretation of the provision
that is the point of the inquiry or provide the wording for
a proposed revision, if this is what the inquirer seeks.
All inquiries shall be directed to:
Managing Director
Technical Services Division
American Welding Society
550 N.W. LeJeune Road
Miami, FL 33126
B3. Interpretation of Provisions of
the Standard
All inquiries shall contain the name, address, and affiliation of the inquirer, and they shall provide enough information for the committee to understand the point of
concern in the inquiry. When the point is not clearly
defined, the inquiry will be returned for clarification. For
efficient handling, all inquiries should be typewritten and
in the format specified below.
Interpretations of provisions of the standard are made by
the relevant AWS technical committee. The secretary of
the committee refers all inquiries to the chair of the particular subcommittee that has jurisdiction over the portion of the standard addressed by the inquiry. The
subcommittee reviews the inquiry and the proposed reply
to determine what the response to the inquiry should
be. Following the subcommittee’s development of the
response, the inquiry and the response are presented to
the entire committee for review and approval. Upon
approval by the committee, the interpretation is an official
B2.1 Scope. Each inquiry shall address one single provision of the standard unless the point of the inquiry
involves two or more interrelated provisions. The provision(s) shall be identified in the scope of the inquiry

obtained only through a written request. Headquarters
staff cannot provide consulting services. However, the
staff can refer a caller to any of those consultants whose
names are on file at AWS Headquarters.
interpretation of the Society, and the secretary transmits
the response to the inquirer and to the Welding Journal
for publication.
B4. Publication of Interpretations
B6. AWS Technical Committees
All official interpretations will appear in the Welding
Journal and will be posted on the AWS web site.
The activities of AWS technical committees regarding
interpretations are limited strictly to the interpretation of
provisions of standards prepared by the committees or to
consideration of revisions to existing provisions on the
basis of new data or technology. Neither AWS staff nor
the committees are in a position to offer interpretive or
consulting services on (1) specific engineering problems,
(2) requirements of standards applied to fabrications
outside the scope of the document, or (3) points not
specifically covered by the standard. In such cases, the
inquirer should seek assistance from a competent engineer experienced in the particular field of interest.
B5. Telephone Inquiries
Telephone inquiries to AWS Headquarters concerning
AWS standards should be limited to questions of a general nature or to matters directly related to the use of the
standard. The AWS Board Policy Manual requires that
all AWS staff members respond to a telephone request
for an official interpretation of any AWS standard with
the information that such an interpretation can be
