3、s the requirements for classification of carbon and low-alloy steel rods for oxyfuel gaswelding. The classification requirements include the mechanical properties of the weld metal. Additional requirementsare included for chemical composition of the rod and for manufacture, sizes, lengths, and packa
4、ging. A guide isappended to the specification as a source of information concerning the classification system employed and the intendeduse of the rods.This specification makes use of both U.S. Customary Units and the International System of Units (SI). Since these arenot equivalent, each system must
5、 be used independently of the other.iiAWS A5.2/A5.2M:2007International Standard Book Number: 978-0-87171-066-6American Welding Society550 N.W.

8、the Use of American Welding Society StandardsAll standards (codes, specifications, recommended practices, methods, classifications, and guides) of the AmericanWelding Society (AWS) are voluntary consensus standards that have been developed in accordance with the rules of theAmerican National Standar
9、ds Institute (ANSI). When AWS American National Standards are either incorporated in, ormade part of, documents that are included in federal or state laws and regulations, or the regulations of other govern-mental bodies, their provisions carry the full legal authority of the statute. In such cases,
10、 any changes in those AWSstandards must be approved by the governmental body having statutory jurisdiction before they can become a part ofthose laws and regulations. In all cases, these standards carry the full legal authority of the contract or other documentthat invokes the AWS standards. Where t
11、his contractual relationship exists, changes in or deviations from requirementsof an AWS standard must be by agreement between the contracting parties.AWS American National Standards are developed through a consensus standards development process that bringstogether volunteers representing varied vi
12、ewpoints and interests to achieve consensus. While AWS administers the processand establishes rules to promote fairness in the development of consensus, it does not independently test, evaluate, orverify the accuracy of any information or the soundness of any judgments contained in its standards.AWS
13、 disclaims liability for any injury to persons or to property, or other damages of any nature whatsoever, whetherspecial, indirect, consequential or compensatory, directly or indirectly resulting from the publication, use of, or relianceon this standard. AWS also makes no guaranty or warranty as to
14、the accuracy or completeness of any informationpublished herein.In issuing and making this standard available, AWS is neither undertaking to render professional or other services for oron behalf of any person or entity, nor is AWS undertaking to perform any duty owed by any person or entity to someo
15、neelse. Anyone using these documents should rely on his or her own independent judgment or, as appropriate, seek theadvice 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 shou
16、ld 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 acceptany and all liabilities for infringement of any patent or trade name items. AWS disclaims liability for the infringement ofany patent or
17、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
18、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 appropriate technical committee. Such requests should be addressed to the American Welding Society,Attention: Managing Directo
19、r, Technical Services Division, 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.These opinions are offered solely as a convenience to users of this standard, and they do not constitu
20、te professionaladvice. Such opinions represent only the personal opinions of the particular individuals giving them. These individualsdo not speak on behalf of AWS, nor do these oral opinions constitute official or unofficial opinions or interpretations ofAWS. In addition, oral opinions are informal
21、 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 mustbe reviewed every five years, and if not revised, it must be either reaffirmed or withdrawn. Comments (recomme
22、ndations,additions, or deletions) and any pertinent data that may be of use in improving this standard are required and should beaddressed to AWS Headquarters. Such comments will receive careful consideration by the AWS A5 Committee onFiller Metals and Allied Materials and the author of the comments
23、 will be informed of the Committees response to thecomments. Guests are invited to attend all meetings of the AWS A5 Committee on Filler Metals and Allied Materials toexpress their comments verbally. Procedures for appeal of an adverse decision concerning all such comments areprovided in the Rules o
24、f Operation of the Technical Activities Committee. A copy of these Rules can be obtained fromthe American Welding Society, 550 N.W.

36、 Rodsfor Oxyfuel Gas Welding, but is included for informational purposes only.This document is the first of the A5.2 specifications that makes use of both U.S. Customary Units and the InternationalSystem of Units (SI). The measurements are not exact equivalents; therefore, each system must be used i
37、ndependently ofthe other, without combining values in any way. In selecting rational metric units, AWS A1.1, Metric Practice Guide forthe Welding Industry, and International Standard ISO 544, Welding consumables Technical delivery conditions forwelding filler materials Type of product, dimensions, t
38、olerances, and markings, are used where suitable. Tables andfigures make use of both U.S. Customary and SI units, which, with the application of the specified tolerances, providesfor interchangeability of products in both U.S. Customary and SI units.The current document is the seventh revision of th
39、e initial joint ASTM/AWS document issued in 1942. As such, it is thesecond oldest document produced by the AWS A5 Committee on Filler Metals and Allied Materials. The first two revi-sions of the 1942 document were developed by the joint committee of the American Welding Society and the AmericanSocie
40、ty for Testing and Materials. The 1969 revision was the first edition developed by the AWS A5 Committee onFiller Metals and Allied Materials. It was subsequently approved by the American National Standards Institute in 1973.This revision adds the requirement for identification of individual rods as
41、shown in italic font in Clause 15, Filler MetalIdentification. In addition, this revision deleted the minimum tensile strength designators for 70, 80, and 90 ksi for theR(X)XX classification.
