2、elding9th EditionSupersedes AWS A5.2/A5.2M:2007Prepared by theAmerican Welding Society (AWS) A5 Committee on Filler Metals and Allied MaterialsUnder the Direction of theAWS Technical Activities CommitteeApproved by theAWS Board of DirectorsAbstractThis specification prescribes the requirements for c
3、lassification of carbon and low-alloy steel rods for oxyfuel gas welding. The classification requirements include the mechanical properties of the weld metal. Additional requirements are included for chemical composition of the rod and for manufacture, sizes, lengths, and packaging. A guide is appen
4、ded to the speci-fication as a source of information concerning the classification system employed and the intended use of the rods.This specification makes use of both U.S. Customary Units and the International System of Units (SI).

8、ifications, 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
9、incorporated in, or made part of, documents that are included in federal or state laws and regulations, or the regulations of other governmen-tal 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 governme
10、ntal 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 fro
11、m 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 administ
12、ers the proc-ess 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 propert
13、y, 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 guarantee or warranty as to the accuracy or completeness of any information pub-lish
14、ed herein.In issuing and making this standard available, AWS is neither 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
15、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. It is assumed that the use of this standard and its provisions is entrusted to appropriately qualified and competent personne
16、l.This standard may be superseded by new editions. This standard may also be corrected through publication of amend-ments or errata, or supplemented by publication of addenda. Information on the latest editions of AWS standards includ-ing amendments, errata, and addenda is posted on the AWS web page
17、 (www.aws.org). Users should ensure that they have the latest edition, amendments, errata, and addenda.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. A
18、WS disclaims liability for the infringement of any patent or product trade name resulting from the use of this standard.AWS does not monitor, police, or enforce compliance with this standard, nor does it have the power to do so.Official interpretations of any of the technical requirements of this st
19、andard 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 Director, Standards Development, 8669 NW 36 St, # 130, Miami, FL 33166 (see Annex B). With regard to technical
20、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 constitute professional advice. Such opinions represent only the personal opinions of the particular individuals givi
21、ng 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 addi-tion, oral opinions are informal and should not be used as a substitute for an official interpretation.This standard is subject to revisi
22、on 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
23、are requested 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 Committees response to the com-ments. Guests are invited to attend all meet
24、ings 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 pro-vided in the Rules of Operation of the Technical Activities Committee. A copy of these Rules can be obtained from t

30、 without combining values in any way. In selecting rational metric units, AWS A1.1, Metric Practice Guide for the Welding Industry, and International Standard ISO 544, Welding consumablesTechnical delivery conditions for welding filler materialsType of product, dimensions, tolerances, and markings,
31、are 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 U.S. Customary and SI units.The current document is the eighth revision of the initial joint ASTM/AWS
32、 document issued in 1942. As such, it is the second 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 American Society for Testing and Mat
33、erials. The 1969 revision was the first edition developed by the AWS A5 Committee on Filler Metals and Allied Materials. It was subsequently approved by the American National Standards Institute in 1973.There are no substantive changes in this revision. The procedure for rounding and the procedure f
34、or requesting a new filler metal classification have been updated.The evolution took place as follows:ASTM A251-42T Tentative Specifications for Iron and Steel Gas Welding RodsAWS A5.2-42TASTM A251-46T Tentative Specifications for Iron and Steel Gas Welding RodsAWS A5.2-46TASTM A251-66T Tentative Sp
