This 2015 edition contains dimensions in metric SI Units and U.S. Customary Units. Clauses 1through 7 constitute a

4、body of rules for the regulation of welding in steel construction. The provisions for Clause 9 havebeen distributed throughout the D1.5 code. Clauses 8, 10, and 11 do not contain provisions, as their analogue D1.1 sec-tions are not applicable to the D1.5 code. Clause 12 contains the requirements for

9、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 state laws and regulati

10、ons, or the regulations of other governmen-tal bodies, their provisions carry the full legal authority of the statute. In such cases, any changes in those AWS stan-dards must be approved by the governmental body having statutory jurisdiction before they can become a part of thoselaws and regulations

11、. In all cases, these standards carry the full legal authority of the contract or other document thatinvokes the AWS standards. Where this contractual relationship exists, changes in or deviations from requirements of anAWS standard must be by agreement between the contracting parties.AWS American N

12、ational Standards are developed through a consensus standards development process that bringstogether volunteers representing varied viewpoints and interests to achieve consensus. While AWS administers the pro-cess and establishes rules to promote fairness in the development of consensus, it does no

13、t independently test, evaluate,or verify the accuracy of any information or the soundness 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,

Such opinions represent o

22、nly the personal opinions of the particular individuals giving them. 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 o

23、fficial interpretation.This standard is subject to revision at any time by the AWS D1 Committee on Structural Welding. It must be reviewedevery five years, and if not revised, it must be either reaffirmed or withdrawn. Comments (recommendations, additions,or deletions) and any pertinent data that ma

24、y be of use in improving this standard are required and should be addressedto AWS Headquarters. Such comments will receive careful consideration by the AWS D1 Committee on StructuralWelding and the author of the comments will be informed of the Committees response to the comments. Guests areinvited

25、to attend all meetings of the AWS D1 Committee on Structural Welding to express their comments verbally.
