8、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 are included in federal or
9、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 can become a part ofthose
10、 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 between the contracting p
11、arties.AWS American National Standards are developed 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 b
33、y many individuals and organizations. The purpose of 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 a
34、nd the AWS B2 Committee on Welding Procedure and Performance Qualification. 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
35、 in the latestedition of AWS A3.0, Standard Welding 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
36、 subject of qualification. The primary document developed by this committee is AWS B2.1,Specification for Welding Procedure and Performance Qualification. This document established the foundation andframework for Standard Welding Procedure Specifications.Comments and suggestions for the improvement
37、of this standard are welcome.
