8、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 National Stan

9、dards 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 such cas

10、es, 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 standards. Wher

11、e 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 varied

12、 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, evalu-ate, or verify the accuracy of any information or the soundness of any judgments contained in its stan

13、dards.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 or warr

14、anty 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 or enti

15、ty 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 provisions i

16、s 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 publicationof amendments or errata. It may also be supplemented by publication of addenda. Information on the latest editions of

17、AWS standards including amendments, errata, and addenda are posted on the AWS web page (www.aws.org). Users shouldensure 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

18、 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.The AWS does not monitor, police, or enforce compliance with this standard, nor does it have the

19、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 request,in wri

20、ting, 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, oral opini

21、ons 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 individualsdo not speak on behalf of A

22、WS, 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 Filler Metals

23、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 pertinent data that may be of use in improving this standard are required and should beaddressed to AWS Headquarters. S

24、uch comments 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 comments.Guests are invited to attend all meetings of the AWS A5 Committee on Filler Metals and Allied Materi

25、als to expresstheir comments verbally. Procedures for appeal of an adverse decision concerning all such comments are provided in theRules of Operation of the Technical Activities Committee.

ScopeThis specification prescribes req

42、uirements for the classification of flux cored stainless steel electrodes for flux cored arcwelding, flux cored stainless steel rods for root pass welding with the gas tungsten arc process, and metal cored stainlesssteel electrodes for gas metal arc welding, gas tungsten arc welding, plasma arc weld

43、ing, submerged arc welding, andany other process to which they may be applied.1The chromium content of undiluted weld metal from these electrodes and rods is not less than 10.5% nominal and theiron content exceeds that of any other element. For purposes of classification, the iron content shall be d

44、erived as the bal-ance element when all other elements are considered to be set at their specified minimum values.Safety and health issues are beyond the scope of this standard and, therefore, are not fully addressed herein. Some safetyand health information can be found in Annex Clauses A5 and A10.

45、 Safety and health information is available fromother sources, including, but not limited to, ANSI Z49.1, Safety in Welding, Cutting, and Allied Processes, and applicablestate and federal regulations.This specification uses both U.S. Customary Units and the International System of Units (SI). The me

46、asurements are notexact equivalents; therefore, each system must be used independently of the other without combining in any way whenreferring to material properties. The specification with the designation A5.22 uses U.S. Customary Units. The specifica-tion A5.22M uses SI Units. The latter are shown

47、 within brackets ( ) or in appropriate columns in tables. Standarddimensions based on either system may be used for sizing of filler metals or packaging or both under A5.22 or A5.22Mspecifications.2.
