8、ommended 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 Institute (ANSI). When AWS American National Standards are either incorporated in,
9、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 such cases, any changes in those AWSstandards must be approved by the governmental body having st
10、atutory 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 standards. Where this contractual relationship exists, changes in or deviations from requirementsof an A
11、WS 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 varied viewpoints and interests to achieve consensus. While the AWS administers theprocess and
12、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 disclaims liability for any injury to persons or to property, or other damages
13、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 or warranty as to the accuracy or completeness of any informationpublished herein.In issuing and
14、 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 someoneelse. Anyone using these documents should rely on his or her own independent
15、 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 entrusted to appropriately qualified and competent personnel.This standard may be supe
16、rseded 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 standard acceptany and all liabilities for infringement of any patent or trade name items. AWS disclai
17、ms 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 it have the power to do so.On occasion, text, tables, or figures are printed incorrectly, constit
18、uting 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, to the appropriate technical committee. Such requests should be addressed to th

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 Allied Materials. It mustbe reviewed every five years, and if not revised, it mus
22、t 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 to AWS Headquarters. Such comments will receive careful consideration by the AWS A5Committee on Filler Me
23、tals 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 Metals andAllied Materials to express their comments verbally. Procedures for appeal of an adverse decision
24、 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.

29、merican Welding Society. The first revision in 1964 was also theresult of the cooperative effort. This revision is the seventh prepared entirely by the AWS A5 Committee on Filler Metalsand Allied Materials. This revision contains new classifications ENiCrFe-13 and ENiCrMo-22. The Rounding-Off Pro-ce
30、dure has been revised. Based on new Rounding-Off Procedure, tensile strength of ENiCrMo-11 in Table 4 has beenrounded up from 585 MPa to 590 MPa, because new rounding off procedure requires rounding to the nearest 10 MPaSubstantive changes are shown in the Italic font.Document DevelopmentASTM B295 5

Scope1.1 This specificati
41、on prescribes requirements for the classification of nickel and nickel-alloy covered electrodes forshielded metal arc welding. It includes those compositions in which the nickel content generally exceeds that of anyother element.11.2 Safety and health issues and concerns are beyond the scope of this
42、 standard and, therefore, are not fully addressedherein. Some safety and health information can be found in the nonmandatory annex, Clauses A5 and A10. Safety andhealth information is available from other sources, including, but not limited to, ANSI Z49.1, Safety in Welding, Cutting,and Allied Proce
43、sses, and applicable federal and state regulations.1.3 This specification makes use of both U.S. Customary Units and the International System of Units (SI). The measure-ments are not exact equivalents; therefore, each system must be used independently of the other without combining inany way when re
44、ferring to material properties. The specification with the designation A5.11 uses U.S. Customary Units.The specification A5.11M uses SI Units. The latter are shown within brackets ( ) or in appropriate columns in tablesand figures. Standard dimensions based on either system may be used for sizing of
45、 filler metal or packaging or bothunder A5.11 or A5.11M specifications.2.
