3、cification prescribes the requirements for the classification of brazing 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,

4、 gold, magnesium, nickel, silver, titanium, and brazing fillermetals 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 m

5、anufacture, sizes, lengths, and packaging. A guide is appended to the 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

6、 Units (SI) and U.S. Customary Units. Since these are notequivalent, each must be used independently of the other.International Standard Book Number: 978-0-87171-790-0American Welding Society8669 Doral Blvd., Suite 130, Doral, FL 33126 2011 by American Welding SocietyAll rights reservedPrinted in th

10、y consensus standards that have been developed in accordance with the rules of theAmerican 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

11、 other governmen-tal bodies, their provisions carry the full legal authority of the statute. In such cases, any changes 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 standa

12、rds carry the full legal authority of the contract or other document that invokes theAWS standards. Where this contractual 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 deve

13、loped through a consensus standards development process that bringstogether volunteers representing varied viewpoints and interests to achieve consensus. While AWS administers theprocess and establishes rules to promote fairness in the development of consensus, it does not independently test, evalu-

14、ate, 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 spe-cial, indirect, consequential, or compensatory, directly or indirectly

This standard may also be corrected through publication of amend-ments or errata, or

18、 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 (www.aws.org). Users should ensure that they havethe latest edition, amendments, errata, and addenda.Publication of this standard does

19、 not authorize infringement of any patent or trade name. Users of this standard accept 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.AWS does not monit

20、or, 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 standard may only be obtained by sending a request, inwriting, to the appropriate technical committee. Such requests should be addressed to

21、the American Welding Society,Attention: Managing Director, Technical Services Division, 8669 Doral Blvd., Suite 130, Doral, FL 33166 (see Annex D).With regard to technical inquiries made concerning AWS standards, oral opinions on AWS standards may be rendered.These opinions are offered solely as a c

22、onvenience to users of this standard, and they do not constitute professional advice.Such opinions represent only the personal opinions of the particular individuals giving them. These individuals do notspeak on behalf of AWS, nor do these oral opinions constitute official or unofficial opinions or

23、interpretations of AWS. Inaddition, 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 mustbe reviewed every five years, and if not revised

24、, 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 comments will receive careful consideration by the AWS A5 Committee on Fi

25、llerMetals 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 toexpress their comments verbally. Procedures for appeal of an adverse

26、decision concerning all such comments are pro-vided in the Rules of Operation of the Technical Activities Committee.
