3、is specification prescribes the requirements for classifications of copper and copper-alloy electrodes for shieldedmetal arc welding. Classification is based on chemical composition, mechanical properties, and usability of theelectrodes. Additional requirements are included for manufacture, sizes, l

4、engths, and packaging. A guide is appended tothe specification as a source of information concerning the classification system employed and intended use of theelectrodes.This specification makes use of both U.S. Customary Units and the International System of Units (SI). Since these arenot equivalen

8、M:2008Statement on 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 theAmeric

9、an National Standards 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 stat

10、ute. In such cases, 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

11、 standards. Where this 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 rep

12、resenting varied viewpoints and interests to achieve consensus. While the AWS administers theprocess and establishes rules to promote fairness in the development of consensus, it does not independently test, evalu-ate, or verify the accuracy of any information or the soundness of any judgments conta

13、ined in its standards.AWS 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 g

14、uarantee or warranty as to 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 an

15、y person or entity to someoneelse. 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. It isassumed that the use of this standard and

16、its provisions are entrusted to appropriately qualified and competent personnel.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 th

17、is standard acceptany and all liabilities for infringement of any patent or trade name items. AWS disclaims liability for the infringement ofany patent or product trade name resulting from the use of this standard.Finally, the AWS does not monitor, police, or enforce compliance with this standard, n

18、or does it have the power to do so.On occasion, text, tables, or figures are printed incorrectly, constituting errata. Such errata, when discovered, are postedon the AWS web page (www.aws.org).Official interpretations of any of the technical requirements of this standard may only be obtained by send

19、ing a request,in writing, to the appropriate technical committee. Such requests should be addressed to the American Welding Society,Attention: Managing Director, Technical Services Division, 550 N.W. LeJeune Road, Miami, FL 33126 (see Annex B).With regard to technical inquiries made concerning AWS s

20、tandards, 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 professionaladvice. Such opinions represent only the personal opinions of the particular individuals giving them. These individualsdo not

21、speak on behalf of AWS, nor do these oral opinions constitute official or unofficial opinions or interpretations ofAWS. 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 Committ

22、ee on Filler Metals and Allied Materials. It mustbe reviewed every five years, and if not revised, it must be either reaffirmed or withdrawn. Comments (recommenda-tions, additions, or deletions) and any pertinent data that may be of use in improving this standard are requiredand should be addressed

23、to AWS Headquarters. Such comments will receive careful consideration by the AWS A5Committee on Filler Metals and Allied Materials and the author of the comments will be informed of the Committeesresponse to the comments. Guests are invited to attend all meetings of the AWS A5 Committee on Filler Me

24、tals andAllied Materials to express their comments verbally. Procedures for appeal of an adverse decision concerning all suchcomments are provided in the Rules of Operation of the Technical Activities Committee. A copy of these Rules can beobtained from the American Welding Society, 550 N.W. LeJeune

26、thout combining in any way. In selecting rational metric units the AWS A1.1, Metric Practice Guide for theWelding Industry, and ISO 544, Welding consumables Technical delivery conditions for welding filler materials Type of product, dimensions, tolerances and markings, are used as guides. Tables and

27、 figures make use of both U.S.Customary and SI Units, which, with the application of the specified tolerances, provide for interchangeability of productsin both U.S. Customary and SI Units.This revision makes adjustments in the chemical composition ranges for classifications ECu, ECuAl-A2, ECuAl-B,E

28、CuNiAl, and ECuMnNiAl to meet with current industry practice. These modified ranges are shown in Italic font inTable 1. It also eliminates the bend test requirements for ECuAl-B, ECuNiAl, and ECuMnNiAl whose elongation in theall-weld metal tension test is less than 20%. The nomograph in the previous

29、 document intended to allow bend tests ofthese classifications has also been removed.Document DevelopmentASTM B225-48T Tentative Specifications for Copper and Copper-Alloy Metal-Arc-Welding ElectrodesAWS A5.6-48TASTM B225-53T Tentative Specifications for Copper and Copper-Alloy Welding ElectrodesAWS

40、 found in the Informative Annex Clauses A5 andA10. Safety and health information is available fromother sources, including, but not limited to, ANSI Z49.1,Safety in Welding, Cutting, and Allied Processes, andapplicable federal and state regulations.This specification makes use of both U.S. Customary

41、Units and the International System of Units (SI). Themeasurements are not exact equivalents; therefore, eachsystem must be used independently of the other withoutcombining in any way when referring to material proper-ties. The specification with the designation A5.6 usesU.S. Customary Units. The spe

42、cification A5.6M uses SIUnits. The latter are shown within brackets or inappropriate columns in tables and figures.
