8、 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 full
9、 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 other
10、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 b
11、ringstogether 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 soun
12、dness 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, whetherspecial, indirect, consequential, or compensatory, directly or indirectly resulting from the publication, use of, or relianceon this s

14、 perform any duty owed by any person or entity to someoneelse. Anyone using these documents should rely on his or her own independent judgment or, as appropriate, seek theadvice of a competent professional in determining the exercise of reasonable care in any given circumstances. It isassumed that t
15、he use of this standard and its provisions are entrusted to appropriately qualified and competent personnel.This standard may be superseded by the issuance of new editions.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 paten
16、t or 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, the AWS does not monitor, police, or enforce comp
17、liance with this standard, nor does it have the power to do so.On occasion, text, tables, or figures are printed incorrectly, constituting errata. Such errata, when discovered, are postedon the AWS web page (www.aws.org).Official interpretations of any of the technical requirements of this standard
18、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, Technical Services Division, 550 N.W.

19、uiries made concerning AWS standards, oral opinions on AWS standards may be rendered.These opinions are offered solely as a convenience to users of this standard, and they do not constitute professionaladvice. Such opinions represent only the personal opinions of the particular individuals giving th
20、em. These individualsdo not speak on behalf of AWS, nor do these oral opinions constitute official or unofficial opinions or interpretations ofAWS. In addition, oral opinions are informal and should not be used as a substitute for an official interpretation.This standard is subject to revision at an
21、y time by the AWS B4 Committee on Mechanical Testing of Welds. It must bereviewed every five years, and if not revised, it must be either reaffirmed or withdrawn. Comments (recommendations,additions, or deletions) and any pertinent data that may be of use in improving this standard are required and
22、should beaddressed to AWS Headquarters. Such comments will receive careful consideration by the AWS B4 Committee onMechanical Testing of Welds and the author of the comments will be informed of the Committees response to thecomments. Guests are invited to attend all meetings of the AWS B4 Committee
23、on Mechanical Testing of Welds toexpress their comments verbally. Procedures for appeal of an adverse decision concerning all such comments areprovided in the Rules of Operation of the Technical Activities Committee.

30、l purposes only.This standard covers the common tests for the mechanical testing of welds. They are defined and illustrated in fiveparts related to testing of groove welds, fillet welds, and stud welds. The tests include: bend tests, tension tests, fracturetoughness tests, soundness tests, shear tes
31、ts, nick-break test, hardness tests, stud weld tests, and selected weldability tests.This document extensively uses American Society for Testing and Materials (ASTM) Standard Methods and specifieshow to use these methods when testing weldments. It takes into consideration the variations in propertie
32、s that can occurbetween different regions (base metal, heat-affected zone, and weld metal) of a weldment.Methods of hardness testing and mechanical property tests for base metals are covered by ASTM standards or theindividual material specification. The joint tests for brazements are covered in AWS
33、C3.2, Standard Methods for Evaluatingthe Strength of Brazed Joints in Shear.This Foreword applies to all five parts. Additional information on the mechanical testing of welded joints may beobtained from the AWS Welding Handbook, Volume 1.The values stated in SI Units and used throughout this documen
34、t are to be regarded as standard. Recommendation forstyle and usage of SI Units may be found in AWS A1.1, Metric Practice Guide for the Welding Industry.An expanded section on weldability testing is included in this edition of B4.0M. Selected weldability test methods aredescribed.Safety Precautions.
35、 Safety precautions shall conform to the latest edition of ANSI Z49.1, Safety in Welding, Cutting,and Allied Processes, published by the American Welding Society.Note: This standard may involve hazardous materials, operations, and equipment. The standard does not purport toaddress all of the safety
36、problems associated with its use. It is the responsibility of the user to establish appropriatesafety and health practices. The user should determine the applicability of any regulatory limitations prior to use.Comments and suggestions for the improvement of this standard are welcome. They should be
37、 sent to the Secretary,AWS B4 Committee on Mechanical Testing of Welds, American Welding Society, 550 N.W.
