2、ditionSupersedes AWS A5.9/A5.9M:2006Prepared by the American Welding Society (AWS) A5 Committee on Filler Metals and Allied MaterialsUnder the Direction of the AWS Technical Activities CommitteeApproved by the AWS Board of DirectorsAbstractThis specification prescribes the requirements for classific
3、ation of solid and composite stainless steel electrodes (both aswire and strip) for gas metal arc welding, submerged arc welding, and other fusion welding processes. It also includeswire and rods for use in gas tungsten arc welding. Classification is based on chemical composition of the filler metal
4、.Additional requirements are included for manufacture, sizes, lengths, and packaging. A guide is appended to the specifi-cation as a source of information concerning the classification system employed and the intended use of the stainless steelfiller metal.This specification makes use of both U.S. C
5、ustomary Units and the International System of Units (SI). Since these are notequivalent, each system must be used independently of the other.International Standard Book Number: 978-0-87171-804-4American Welding Society550 N.W.

9、ry 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 o
10、f 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 stand
11、ards 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 dev
12、eloped through a consensus standards development process that bringstogether volunteers representing 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, e
13、valu-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 indire
14、ctly resulting from the publication, use of, or reliance on thisstandard. AWS also makes no guarantee or warranty as to 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
15、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 judgment or, as appropriate, seek theadvice of a competent professional in determining the exercise
16、of reasonable care in any given circumstances. It isassumed that the use of this standard and its provisions is entrusted 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 am
17、endments or errata. It may also be supplemented by publication of addenda. Information on the latest editionsof AWS standards 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.
18、Publication of this standard does 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
19、 this standard.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, constituting errata. Such errata, when discovered, are postedon the AWS web page (www.aws.org).Official interp
20、retations 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 the American Welding Society,Attention: Managing Director, Technical Services Division, 550 N.W. LeJeune
21、Road, Miami, FL 33126 (see Annex B).With regard to technical inquiries made concerning AWS standards, 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 on
22、ly the personal opinions of the particular individuals giving them. These individualsdo not 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 of
23、ficial 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 must be either reaffirmed or withdrawn. Comments (recommendations,additions, or deletions) and any pertine

36、s are “ER” for solid wires that may be used as electrodes or rods; “EC” for composite coredor stranded wires; and “EQ” for strip electrodes (see Table 1).3.2 Materials may be classified under more than one classification provided they meet all the requirements of thoseclassifications as specified in

Rounding-Off ProcedureFor the purpose of determining compliance with the requirements of this standard, the actual test values obtained shallbe subjected to the rounding-off rules of ASTM E 29 or Rule A in Clause B.3 of ISO 80000-1 (the
39、results are the same).If the measured values are obtained by equipment calibrated in units other than those of the specified limit, the measuredvalues shall be converted to the units of the specified limit before rounding off. If an average value is to be compared to the specified limit, rounding of
40、f shall be done only after calculating the average. An observed or calculated value shall be rounded to the nearest unit in the last right-hand place of figures used in expressing the limiting values for otherquantities.
