3、bstractClassification requirements are specified for fluxes and solid and composite metal cored electrodes for electroslagwelding. The requirements for electrodes include chemical composition of the electrode for solid electrodes and of weldmetal for metal cored electrodes. Requirements for fluxes i

4、nclude the mechanical properties and soundness of weldmetal taken from a groove weld made with a particular electrode using a prescribed welding procedure. Standard electrodesizes, marking, and packaging requirements are included.This specification makes use of both U.S. Customary Units and the Inte

5、rnational System of Units (SI). Since these arenot equivalent, each system must be used independently of the other.Key WordsFiller metal specifications, low-alloy steel electrodes, carbon steel electrodes, arc welding electrodes, metal cored electrodes, electroslag weldingiiANSI/AWS A5.25/A5.25M-97

9、tement 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 theAmerican Nation

10、al 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 statute. In s

11、uch 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 standard

12、s. 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 representing

13、 varied viewpoints and interests to achieve consensus. While the AWS administers the pro-cess 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 i

14、ts 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 guarantee

15、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 any person

16、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 its provi

17、sions 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 this standa

18、rd 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, nor does i

19、t 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 sending a req

20、uest, inwriting, 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 standards,

21、 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 individuals donot speak on

22、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 Committee on Fil

23、ler Metals. It must be reviewed everyfive years, and if not revised, it must be either reaffirmed or withdrawn. Comments (recommendations, additions, ordeletions) and any pertinent data that may be of use in improving this standard are required and should be addressed toAWS Headquarters. Such commen

24、ts will receive careful consideration by the AWS A5 Committee on Filler Metals andthe author of the comments will be informed of the Committees response to the comments. Guests are invited to attendall meetings of the AWS A5 Committee on Filler Metals to express their comments verbally. Procedures f

25、or appeal ofan adverse decision concerning all such comments are provided in the Rules of Operation of the Technical ActivitiesCommittee. A copy of these Rules can be obtained from the American Welding Society, 550 N.W. LeJeune Road,Miami, FL 33126.This page is intentionally blank.ivANSI/AWS A5.25/A

47、irst of the A5.25 specifications to use both U.S. Customary Units and the International Systemof Units (SI). The measurements are not exact equivalents; therefore, each system must be used independently of theother, without combining in any way. In selecting rational metric units, the ANSI/AWS A1.1,

48、 Metric Practice Guide forthe Welding 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 figures make use of both U.S.Customary and SI Units, which with the applica

49、tion of the specified tolerances provide for interchangeability of productsin both U.S. Customary and SI Units.Added Annex B (Informative), Guidelines for Preparation of Technical Inquiries.The current document is the second revision of this specification, as shown below:Document DevelopmentAWS A5.25-78 Specification for Consumables Used for Electroslag Welding of Carbon and High StrengthLow Alloy SteelsANSI/AWS A5.25-91 Specification for Carbon and Low Alloy Steel Electrodes and Fluxes for Electroslag WeldingANSI/AWS A5.25-97R Specification for Carbon and Low-Alloy Steel Electrodes
