3、ing structural welds used in the manufacture and repair of earthmoving,construction, and agricultural equipment. Such equipment is defined as self-propelled, on- and off-highway machineryand associated implements. Manufacturers responsibilities are presented as they relate to the welding practices t
4、hat havebeen proven successful within the industry in the production of weldments on this equipment. Basic dimensional welddetails are defined and interpreted for application throughout the document. Provisions are made to identify base metalsused in these weldments. Procedures to ensure that they a
5、re welded with compatible, identifiable welding processes andconsumables are included with consideration given to factors that affect weldability.International Standard Book Number: 978-0-87171-776-4American Welding Society550 N.W.

9、 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 incorporated in, ormade part of, documents that are included in federal or state laws and regulations, or the regul
10、ations of other governmen-tal bodies, their provisions carry the full legal authority of the statute. In such cases, any changes in those AWS standardsmust be approved by the governmental body having statutory jurisdiction before they can become a part of those laws and regulations. In all cases, th
11、ese standards carry the full legal authority of the contract or other document that invokesthe AWS standards. Where this contractual relationship exists, changes in or deviations from requirements of an AWSstandard must be by agreement between the contracting parties.AWS American National Standards
12、are developed through a consensus standards development process that brings togethervolunteers representing varied viewpoints and interests to achieve consensus. While the AWS administers the process andestablishes rules to promote fairness in the development of consensus, it does not independently
13、test, evaluate, or verify theaccuracy 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, whether special, indirect, consequential, or compensatory, directly or in
14、directly 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 information published herein.In issuing and making this standard available, AWS is neither undertaking to render professional or other servi
15、ces 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 own independent judgment or, as appropriate, seek theadvice of a competent professional in determining the exerc
16、ise 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 standard may be superseded by the issuance of new editions. Users should ensure that they have the latest edition.Pub
17、lication of this standard does not authorize infringement of any patent or trade name. Users of this standard accept anyand all liabilities for infringement of any patent or trade name items. AWS disclaims liability for the infringement of anypatent or product trade name resulting from the use of th
18、is 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 incorrectly, constituting errata. Such errata, when discovered, are postedon the AWS web page (www.aws.org).Official
19、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. Le
20、Jeune Road, Miami, FL 33126 (see Annex E).With regard to technical inquiries made concerning AWS standards, oral opinions on AWS 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 repres
21、ent 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 ofAWS. In addition, oral opinions are informal and should not be used as a substitute for
22、 an official interpretation.This standard is subject to revision at any time by the AWS D14 Committee on Machinery and Equipment. It must bereviewed every five years, and if not revised, it must be either reaffirmed or withdrawn. Comments (recommendations,additions, or deletions) and any pertinent d
23、ata 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 D14 Committee onMachinery and Equipment and the author of the comments will be informed of the Committees response to the comments.Gu
24、ests are invited to attend all meetings of the AWS D14 Committee on Machinery and Equipment to express their com-ments verbally. Procedures for appeal of an adverse decision concerning all such comments are provided in the Rules ofOperation of the Technical Activities Committee. A copy of these Rule
