3、n requirements are specified for solid and composite (flux cored and metal cored) electrodes for electro-gas welding. The requirements include chemical composition of the electrode for solid electrodes and of weld metal forcomposite (cored) electrodes, in addition to the mechanical properties and so

4、undness of weld metal taken from a grooveweld made with these electrodes using the prescribed welding procedure. Standard electrode sizes, marking, and packag-ing requirements are included.This specification makes use of both U.S. Customary Units and the International System of Units (SI). Since the

9、 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 Standards Institute (ANSI). When AWS American National

10、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 cases, any changes in those AWSstandards must be appro

11、ved 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. Where this contractual relationship exists, changes in

12、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 viewpoints and interests to achieve consensus. Whi

13、le 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 standards.AWS disclaims liability for any injury to per

14、sons 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.

19、gures 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 writing, to the appropriate technical committee. S

20、uch 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 A).With regard to technical inquiries made concerning AWS standards, oral opinions on AWS standards may be rendered.These opin

21、ions 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 AWS, nor do these oral opinions constitute offic

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. It must be reviewed everyfive years, and if no

23、t 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 comments will receive careful consideration by the AWS A5 Commit
