The annex lists themanner by which the filler metal specification may refer to a
4、ppropriate requirements in this specification.This specification makes use of both U.S. Customary Units and the International System of Units (SI).

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

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22、vised, it must be either reaffirmed or withdrawn.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
