13、ssifications, 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 incorporated in, ormade part of, documents that a

14、re 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 body having statutory jurisdiction before they

15、 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 requirementsof an AWS standard must be by agreement

16、 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 AWS administers the processand establishes rules to promote fairnes

17、s in the development of consensus, it does not independently test, evaluate, orverify 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 other damages of any nature whatsoever, whetherspeci

20、 of a competent professional in determining the exercise of reasonable care in any given circumstances.This standard may be superseded by the issuance of new editions.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

21、trade name. Users of this standard acceptany and all liabilities for infringement of any patent or trade name items. AWS disclaims liability for the infringement ofany patent or product trade name resulting from the use of this standard.Finally, AWS does not monitor, police, or enforce compliance wi

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

23、be obtained by sending a request,in writing, to the Managing Director, Technical Services Division, American Welding Society, 550 N.W. LeJeune Road,Miami, FL 33126 (see Annex A). With regard to technical inquiries made concerning AWS standards, oral opinionson AWS standards may be rendered. However,

24、 such opinions represent only the personal opinions of the particularindividuals giving them.

The user needs asignificant knowledge of welding and accepts fullresponsibility for the performance of the weld and forproviding the engineering capability, qualified person-nel, and proper equipment to implement this SWPS.Application.

37、This SWPS is to be used only as per-mitted by AWS B2.1, Specification for Procedure andPerformance Qualification, and the applicable fabri-cation document(s) such as code, specification, orcontract document(s).
