7、se 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 rules of theAmerican National Standards In

8、stitute (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 governmentalbodies, their provisions carry the full legal authority of the statute. In such cases, any ch

9、anges in those AWS standardsmust be approved by the governmental body having statutory jurisdiction before they can become a part of those lawsand regulations. In all cases, these standards carry the full legal authority of the contract or other document that invokesthe AWS standards. Where this con

10、tractual relationship exists, changes in or deviations from requirements of an AWSstandard must be by agreement between the contracting parties.AWS American National Standards are developed through a consensus standards development process that bringstogether volunteers representing varied viewpoint

11、s and interests to achieve consensus. While AWS administers the processand establishes rules to promote fairness 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 discla

It isassumed that the use of this standard and its provisions is entrusted to a

15、ppropriately qualified and competent personnel.This standard may be superseded by new editions. This standard may also be corrected through publication of amendmentsor errata, or supplemented by publication of addenda.

18、 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, Standards Development, 8669 NW 36 St, # 130, Miami, FL 33166 (see

19、 Annex E). Withregard to technical inquiries made concerning AWS standards, oral opinions on AWS standards may be rendered. Theseopinions are offered solely as a convenience to users of this standard, and they do not constitute professional advice.Such opinions represent only the personal opinions o

20、f the particular individuals giving them. These individuals do notspeak on behalf of AWS, nor do these oral opinions constitute official or unofficial opinions or interpretations of AWS.In addition, oral opinions are informal and should not be used as a substitute for an official interpretation.This

21、 standard is subject to revision at any time by the AWS B2 Committee on Procedure and Performance Qualification.It must be reviewed every five years, and if not revised, it must be either reaffirmed or withdrawn. Comments (recommen-dations, additions, or deletions) and any pertinent data that may be

22、 of use in improving this standard are required andshould be addressed to AWS Headquarters. Such comments will receive careful consideration by the AWS B2 Committeeon Procedure and Performance Qualification and the author of the comments will be informed of the Committeesresponse to the comments. Gu

23、ests are invited to attend all meetings of the AWS B2 Committee on Procedure and Perfor-mance Qualification to express their comments verbally. Procedures for appeal of an adverse decision concerning allsuch comments are provided in the Rules of Operation of the Technical Activities Committee. A cop

42、ng Procedure Qualification4.1 General. A soldering procedure qualification provides test data for assessing the properties of a soldered joint. It isthe obligation of manufacturers to produce soldered assemblies that have properties suitable for the application. Theproof of production solder soundne

43、ss is determined by the type and extent of testing and examination applied, which isthe responsibility of the Referencing Document.4.1.1 Each soldering procedure shall be qualified to establish the properties that are expected to result from its appli-cation to production soldered joints. To qualify

44、 a soldering procedure, the following steps are necessary:(1) The employer shall prepare a preliminary soldering procedure specification (SPS) to be used in making a solderedtest assembly. Any format may be used for the SPS, provided all qualification variables and other applicable informationare in

45、cluded.(2) The actual conditions used in making the soldered test assembly and the results of the required examination andspecimen testing shall be recorded on a soldering procedure qualification record (SPQR). Any format may be used, pro-vided all essential and nonessential qualification variables

46、are addressed.(3) When the results meet the acceptance criteria of this document, the qualifying company shall certify by signatureand date that the soldering and testing for procedure qualification are in accordance with AWS B2.3/B2.3M.(4) If the results do not meet the acceptance criteria, a new s

47、oldered test assembly shall be prepared. Soldered test as-semblies shall not be repaired.(5) Procedures qualified by one employer are not transferable to another employer.4.1.2 During the making of procedure test assemblies for qualification (see Table A.1), the solderer or soldering oper-ator shall

48、 be under the full supervision and control of the Qualifier. The Qualifier is responsible for ensuring proper:(1) Preparation of workpieces for soldering,(2) Documentation of the soldering test assembly variables,(3) Preparation of specimens from the completed soldered test assembly,(4) Performance

49、of examination and mechanical tests, and(5) Documentation of results.4.1.3 A change in qualification variable beyond the allowed limits of 4.3 Qualification Variables shall require requal-ification of the SPS and preparation of a new SPS. Changes in other variables shall not require requalification, providedsuch changes are documented in a revised SPS.4.1.4 SPQRs shall not be revised, except to correct errors or add omitted information. However, all such changesshall be identified and dated on the SPQR.4.1.5 SPSs and SPQRs shall be identified according to a system that allows traceability b
