8、ications, 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 Standards are either inco

9、rporated 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 b

10、ody 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 or deviations from requir

11、ementsof 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 the AWS administers th

12、eprocess 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 persons or to property, or o

13、ther 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 warranty as to the accuracy or completeness of any informationpublished herein.I

14、n 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 these documents should rely on his or her ow

15、n 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 qualified and competent personnel.This standar

17、. AWS disclaims liability for the infringement ofany patent 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, text, tables, or figures are printed incorre

18、ctly, 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 ad

19、dressed 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 on AWS standards may be rendered.These opinions are offered solely a

20、s 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 opinion

21、s 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 mustbe reviewed every five years, and if not re

22、vised, 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 careful consideration by the AWS A5 Committee

23、on FillerMetals and Allied Materials and the author of the comments will be informed of the Committees 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 an adver

Scope1.1 This specification prescribes requirements for stan-dard sizes and packages of welding filler metals and theirphysical attributes, such as product appearance andidentification.1.2 This specification applies to

35、 covered electrodes withboth solid and tubular core wires; bare solid and tubularwires on spools, coils, and drums, or in straight lengths;and solid and sintered strip electrodes. It applies to allfusion welding processes, except brazing, braze welding,and thermal spraying, or granular metallic or m

36、ineralproducts, such as submerged arc fluxes, or other suchproducts used in fusion welding processes.1.3 Safety and health issues and concerns are beyond thescope of this standard and are, therefore, not fullyaddressed herein. Safety and health information is avail-able from other sources, including

37、, but not limited to,ANSI Z49.1, Safety in Welding, Cutting, and AlliedProcesses, and applicable federal and state regulations.1.4 This specification makes use of both U.S. CustomaryUnits and the International System of Units (SI). Themeasurements are not exact equivalents; therefore, eachsystem mus

38、t be used independently of the other withoutcombining in any way. The specification with the desig-nation A5.02 uses U.S. Customary Units. The specifica-tion A5.02M uses SI Units. The latter are shown withinbrackets or in appropriate columns in tables and fig-ures. Standard dimensions based on eithe
