7、S D15.2/D15.2M:2013iiiStatement on the Use of American Welding Society 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 ru
8、les 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 regulations of other governmen-tal bodies, their provisions carry the full legal autho
9、rity 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 andregulations. In all cases, these standards carry the full legal authority of the contract or other document tha
10、t invokes theAWS standards. Where this contractual relationship exists, 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 bringstoget
11、her volunteers representing varied viewpoints and interests to achieve consensus. While 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 j
12、udgments contained in its standards.AWS disclaims liability for any 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.

This standard may also be corrected through publication of amend-ments or errata, or supplemented by publication of addenda. Information on the latest editi
16、ons of AWS standards includ-ing amendments, errata, and addenda is posted on the AWS web page (www.aws.org). Users should ensure that they havethe latest edition, amendments, errata, and addenda.Publication of this standard does not authorize infringement of any patent or trade name. Users of this s
17、tandard 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 this standard.AWS does not monitor, police, or enforce compliance with this standard, nor does it have t
18、he power to do so.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 Ser
19、vices Division, 8669 Doral Blvd., Suite 130, Doral, FL 33166 (see AnnexF). With regard to technical inquiries made concerning AWS standards, oral opinions on AWS standards may be ren-dered. These opinions are offered solely as a convenience to users of this standard, and they do not constitute profe
20、ssionaladvice. 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 ofAWS. In addition, oral opinions are informal and sho
21、uld not be used as a substitute for an official interpretation.This standard is subject to revision at any time by the AWS D15 Committee on Railroad Welding. It must be reviewedevery five years, and if not revised, it must be either reaffirmed or withdrawn. Comments (recommendations, additions,or de
22、letions) and any pertinent data that may be of use in improving this standard are required and should be addressedto AWS Headquarters. Such comments will receive careful consideration by the AWS D15 Committee on RailroadWelding and the author of the comments will be informed of the Committees respon
23、se to the comments. Guests areinvited to attend all meetings of the AWS D15 Committee on Railroad Welding to express their comments verbally.Procedures for appeal of an adverse decision concerning all such comments are provided in the Rules of Operation of theTechnical Activities Committee.

34、ils and RelatedRail Components for Use by Rail Vehicles, but is included for informational purposes only.This recommended practice establishes standards for the joining, repair, maintenance and inspection of rail welds, andthe welding of related rail components. It was developed and is maintained by
35、 the Subcommittee on Track Weldingwithin the AWS Committee on Railroad Welding.The welding of rails and related rail components for use by rail vehicles is vital to the safe and economical operation ofAmerican railroads. This subcommittee has endeavored to develop these recommended practices to serv
36、e as a guidelinefor the railroad and related industries in the establishment of track welding specifications. The subcommittee is made upof individuals from all segments of the railroad industry, both users and suppliers, and representatives of both theAssociation of American Railroads and the Ameri
37、can Railway Engineering and Maintenance-of-Way Association.The purpose of this document is to provide a single comprehensive source of information that will be used throughout therailroad industry. It should act as a guideline towards improving welding quality through the economical joining andrepai
38、r of rail and rail components.The evolution of AWS D15.2, Recommended Practices for the Welding of Rails and Related Rail Components for Useby Rail Vehicles, is shown below:ANSI/AWS D15.294, Recommended Practices for the Welding of Rails and Related Rail Components for Use by Rail VehiclesAWS D15.2:
