8、ary 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 regulations

9、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 can become a part ofthose laws and regulations. In all cases, these stan

10、dards 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 between the contracting parties.AWS American National Standards are deve

11、loped through a consensus standards development process that bringstogether volunteers representing varied viewpoints and interests to achieve consensus.

The need for pretested welding procedures that are supported by adequate testdata and that satisfy the technical requirements for the commonly used construction codes and specifications has beenexpressed by many individuals and organizations. The purpose of

33、 a welding procedure qualification is to provide test datafor assessing the properties of a weld joint.This Welding Procedure Specification is an outgrowth of the coordinated work of the Welding Procedures Committee ofthe Welding Research Council and the AWS B2 Committee on Welding Procedure and Per

TheWelding Procedures Committee has provided the test data documented by a Summary of Procedure Qualification Records.The welding terms used in this specification shall be interpreted in accordance with the definitions given in the latestedition of AWS A3.0, Standard Welding

35、Terms and Definitions, Including Terms for Adhesive Bonding, Brazing, Soldering,Thermal Cutting, and Thermal Spraying.The AWS Committee on Welding Procedure and Performance Qualification was formed in 1979 to provide weldingstandards concerning the subject of qualification.

40、tion (SWPS) were derived fromthe above-listed Procedure Qualification Records(PQRs) which were reviewed and validated underthe auspices of the Welding Research Council. ThisSWPS is not valid using conditions and variablesoutside the ranges listed. The American WeldingSociety considers that this SWPS

41、 presents infor-mation for producing an acceptable weld using theconditions and variables listed. The user needs asignificant knowledge of welding and accepts fullresponsibility for the performance of the weld andfor providing the engineering capability, qualifiedpersonnel, and proper equipment to i

42、mplement thisSWPS.Application. This SWPS is to be used only aspermitted by the applicable fabrication document(s);such as code, specification, or contract docu-ment(s). The fabrication document(s) should specifythe engineering requirements such as design, needfor heat treatment, fabricating toleranc

43、es, qualitycontrol, and examination and tests applicable to theend product.Users Responsibility. An SWPS does not replaceor substitute for fabrication codes, specifications,contract requirements, or capability and judgmenton the part of the user. An SWPS is to be used onlyas permitted by the applica

44、ble fabrication code,specification, or contract document.The ability to produce production welds havingproperties suitable for the application depends uponsupplementing the SWPS with appropriate perfor-mance qualification tests and sound engineeringjudgment. The user is responsible for the quality a

45、ndperformance of the final product in accordance withthe provisions of the fabrication document(s).Supplementary Instructions. To adapt this SWPSto a specific application, a user may issue supple-mentary instructions. Such instructions may consistof tighter fit-up tolerances, higher minimum preheatt

46、emperature or any other instructions necessary toproduce a weldment that meets the requirements ofthe fabrication document(s). These instructions shallnot be less restrictive than provided in the SWPS.Safety. Safety precautions shall conform to thelatest edition of ANSI Z49.1, Safety in Welding,Cutt
