1、Specification forFiller Metals forBrazing andBraze WeldingAWS A5.8M/A5.8:2011An American National StandardAWS A5.8M/A5.8:2011An American National StandardApproved by theAmerican National Standards InstituteJune 17, 2011Specification for Filler Metals for Brazing and Braze Welding10th EditionSupersed

2、es AWS A5.8/A5.8M:2004Prepared 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 the classification of braz

3、ing filler metals for brazing and braze welding.The chemical composition, physical form, and packaging of more than 120 brazing filler metals are specified. The brazingfiller metal groups described include aluminum, cobalt, copper, gold, magnesium, nickel, silver, titanium, and brazing fillermetals

4、for vacuum service. Information is provided concerning the liquidus, the solidus, the brazing temperature range, and general areas of application recommended for each brazing filler metal. Additional requirements are included for manufacture, sizes, lengths, and packaging. A guide is appended to the

5、 specification as a source of information concerningthe classification system employed and the intended use of the brazing filler metals for brazing and braze welding.This specification makes use of both the International System of Units (SI) and U.S. Customary Units. Since these are notequivalent,

6、each must be used independently of the other.International Standard Book Number: 978-0-87171-790-0American Welding Society550 N.W.

9、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 Standards Institut

10、e (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 governmen-tal bodies, their provisions carry the full legal authority of the statute. In such cases, any change

11、s in those AWS standardsmust be approved by the governmental body having statutory jurisdiction before they can become a part of those laws andregulations. In all cases, these standards carry the full legal authority of the contract or other document that invokes theAWS standards. Where this contrac

12、tual relationship exists, changes in or deviations from requirements of an AWS stan-dard 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 viewpoints

13、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 contained in its standards.AWS di

14、sclaims liability for any injury to persons or to property, or other damages of any nature whatsoever, whether spe-cial, indirect, consequential, or compensatory, directly or indirectly resulting from the publication, use of, or reliance on thisstandard. AWS also makes no guarantee or warranty as to

15、 the accuracy or completeness of any information published 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 som

16、eoneelse. 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 its provisions are entrus

17、ted to appropriately qualified and competent personnel.This standard may be superseded by the issuance of new editions. This standard may also be corrected through publica-tion of amendments or errata. It may also be supplemented by publication of addenda. Information on the latest editionsof AWS st

18、andards including amendments, errata, and addenda are posted on the AWS web page (www.aws.org). Usersshould 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 accep

19、t anyand all liabilities for infringement of any patent or trade name items. AWS disclaims liability for the infringement of anypatent or product trade name resulting from the use of this standard.The AWS does not monitor, police, or enforce compliance with this standard, nor does it have the power

20、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 sending a request,in writing,

21、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 D).With regard to technical inquiries made concerning AWS standards, oral opinions on

22、 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 speak on behalf of AWS, no

23、r 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 Committee on Filler Metals and Al

24、lied Materials. It mustbe 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 beaddressed to AWS Headquarters. Such co

25、mments will receive careful consideration by the AWS A5 Committee on FillerMetals 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 meetings of the AWS A5 Committee on Filler Metals and Allied Materials

26、toexpress 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 theAmerican Welding Society, 550 N.W. LeJeune Road, Miami, FL 33126.A
