7、ce 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 regulations of other govern-mental bodies, their provisions carry the fu

8、ll 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 can become a part ofthose laws and regulations. In all cases, these standards carry the full legal authority of the contract or othe

9、r documentthat invokes the AWS standards. Where this contractual relationship exists, changes in or deviations from requirementsof an AWS standard must be by agreement between the contracting parties.AWS American National Standards are developed through a consensus standards development process that

10、 bringstogether volunteers representing varied viewpoints and interests to achieve consensus. While the 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 so

The data to support this Standard Welding

33、Procedure Specification (SWPS) have been derived fromthe above listed Procedure Qualification Records (PQRs) which were reviewed and validated under the auspicesof the Welding Research Council. This SWPS is not valid using conditions and variables outside the rangeslisted. The American Welding Socie

34、ty considers that this SWPS presents information for producing anacceptable weld using the conditions and variables listed. The user needs a significant knowledge of weldingand accepts full responsibility for the performance of the weld and for providing the engineering capability,qualified personne

35、l, and proper equipment to implement this SWPS.Application. This SWPS is to be used only as permitted by AWS B2.1, Specification for Procedure and Per-formance Qualification, and the applicable fabrication document(s) such as code, specification, or contractdocument(s). The fabrication document(s) s

36、hould specify the engineering requirements such as design,need for heat treatment, fabricating tolerances, quality control, and examination and tests applicable to theend product.Users Responsibility. An SWPS does not replace or substitute for fabrication codes, specifications, contractrequirements,

37、 or capability and judgment on the part of the user. An SWPS is to be used only as permitted bythe applicable fabrication code, specification, or contract document.The ability to produce production welds having properties suitable for the application depends upon supple-menting the SWPS with appropr

38、iate performance qualification tests and sound engineering judgment. Theuser is responsible for the quality and performance of the final product in accordance with the provisions ofthe fabrication document(s).Supplementary Instructions. To adapt this SWPS to a specific application, a user may issue

39、supplementaryinstructions. Such instructions may consist of tighter fit-up tolerances, higher minimum preheat temperature,or any other instructions necessary to produce a weldment that meets the requirements of the fabricationdocument(s). These instructions shall not be less restrictive than provide

40、d in the SWPS.Safety. Safety precautions shall conform to the latest edition of ANSI Z49.1, Safety in Welding, Cutting, andAllied Processes, published by the American Welding Society.This specification may involve hazardous materials, operations, and equipment. The specification does notpurport to a

41、ddress all of the safety problems associated with its use. It is the responsibility of the user toestablish appropriate safety and health practices.
