Specification For AL and AL Alloy Electrodes
  AWS A5.3/A5.3M:1999 (R2007)An American National Standard Specification forAluminum andAluminum-AlloyElectrodes forShielded MetalArc Welding  550 N.W. LeJeune Road, Miami, FL 33126 AWS A5.3/A5.3M:1999 (R2007)An American National StandardApproved by theAmerican National Standards InstituteFebruary 11, 1999 Specification forAluminum and Aluminum-AlloyElectrodes for ShieldedMetal Arc Welding Supersedes ANSI/AWS A5.3-91 Prepared by theAmerican Welding Society (AWS) A5 Committee on Filler Metals and Allied MaterialsUnder the Direction of theAWS Technical Activities CommitteeApproved by theAWS Board of Directors Abstract This specification prescribes requirements for the classification of covered (flux coated) E1100, E3003, and E4043aluminum-alloy electrodes for shielded metal arc welding. Tests conducted for classification are chemical analysis of thecore wire as well as tensile and bend tests from groove weld test assemblies fabricated with each of two sizes of electrodefor each classification. Standard electrode sizes, electrode identification, and chemical composition limits are specified.This specification makes use of both U.S. Customary Units and the International System of Units (SI). Since these arenot equivalent, each system must be used independently of the other.

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 cases, any changes in those AWSstandards must be approved by the governmental body having statutory jurisdiction before they can become a part of those 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 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. While AWS administers the processand establishes rules to promote fairness in the development of consensus, it does not independently test, evaluate, orverify 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, whetherspecial, indirect, consequential or compensatory, directly or indirectly resulting from the publication, use of, or relianceon this standard.

Users of this standard acceptany and all liabilities for infringement of any patent or trade name items. AWS disclaims liability for the infringement of any patent or product trade name resulting from the use of this standard.Finally, 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 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 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 opinions onAWS 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 AWS, nor do these oral opinions constitute official or unofficial opinions or interpretations of AWS. 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 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 andshould beaddressed to AWS Headquarters. Such comments will receive careful consideration by the AWS A5 Committee onFiller Metals and Allied Materials and the author of the comments will be informed of the Committee’s response to thecomments. Guests are invited to attend all meetings of the AWS A5 Committee on Filler Metals and Allied Materials toexpress their comments verbally. Procedures for appeal of anadverse decision concerning all such comments areprovided in the Rules of Operation of the Technical Activities Committee.
