2、 Welding10th EditionSupersedes AWS A5.5/A5.5M:2006Prepared by theAmerican Welding Society (AWS) A5 Committee on Filler Metals and Allied MaterialsUnder the Direction of theAWS Technical Activities CommitteeApproved by theAWS Board of DirectorsAbstractThis specification prescribes the requirements fo
3、r classification of low-alloy steel covered electrodes used for shieldedmetal arc welding. The requirements include chemical composition and mechanical properties of weld metal, weld metalsoundness, usability tests of electrodes, and moisture tests of the low-hydrogen electrode covering. Requirement
4、s forstandard sizes and lengths, marking, manufacturing, and packaging are also included.Optional supplemental requirements include tests for absorbed moisture in the electrode covering and for diffusiblehydrogen in the weld metal.This specification makes use of both U.S. Customary Units and the Int
5、ernational System of Units (SI). Since these are notequivalent, each system must be used independently of the other.ISBN: 978-0-87171-850-1 2014 by American Welding SocietyAll rights reservedPrinted in the United States of AmericaPhotocopy Rights.

8、ty 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 Standards Institute (ANSI). When AWS Ame
9、rican 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 governmen-tal bodies, their provisions carry the full legal authority of the statute. In such cases, any changes in those AWS standar
10、dsmust be approved by the governmental body having statutory jurisdiction before they can become a part of those laws andregulations. In all cases, these standards carry the full legal authority of the contract or other document that invokes theAWS standards. When this contractual relationship exist
11、s, changes in or deviations from requirements of an AWS stan-dard 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 achiev
12、e 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 standards.AWS disclaims liability for a
13、ny injury to persons or to property, or other damages of any nature whatsoever, whether spe-cial, indirect, consequential, or compensatory, directly or indirectly resulting from the publication, use of, or reliance onthis standard. AWS also makes no guarantee or warranty as to the accuracy or comple
14、teness of any information publishedherein.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 entity to someoneelse. Anyone using t
15、hese 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 are entrusted to appropriately qua
16、lified and competent personnel.This standard may be superseded 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 accept anyand all liabilities for inf
17、ringement of any patent or trade name items. AWS disclaims liability for the infringement of anypatent 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, t
18、ext, 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 tech
19、nical committee. Such requests should be addressed to the American Welding Society,Attention: Managing Director, Technical Services Division, 8669 NW 36th St, # 130, Miami, FL 33126 (see Annex B).With regard to technical inquiries made concerning AWS standards, oral opinions on AWS standards may be
20、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 opinio
21、ns 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 and Allied Materials. It mus
22、tbe 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. Such comments will receive ca
23、reful 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 com-ments. Guests are invited to attend all meetings of the AWS A5 Committee on Filler Metals and Allied Materials toexpress their commen
24、ts verbally. Procedures for appeal of an adverse decision concerning all such comments are pro-vided in the Rules of Operation of the Technical Activities Committee.
