2 IiiAWS :2014 Statement on the Use 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 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 governmen-tal bodies, their provisions carry the full legal authority of the statute. In such cases, any changes 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 contractual relationship exists, changes in or deviations from requirements of an AWSstandard must be by agreement between the contracting American National Standards are developed through a consensus standards development process that brings to-gether volunteers representing varied viewpoints and interests to achieve consensus.

3 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 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 standard.

5 Such requests should be addressed to the American Welding Society,Attention: Managing Director, Technical Services Division, 8669 NW 36 St, # 130, Miami, FL 33166 (see Annex J).With regard to technical inquiries made concerning AWS standards, oral opinions on AWS standards may be opinions are offered solely as a convenience to users of this standard, and they do not constitute professional ad-vice. Such opinions represent only the personal opinions of the particular individuals giving them. These individuals donot 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 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.

6 Comments (recommendations, additions,or deletions) and any pertinent data that may be of use in improving this standard are required and should be addressed toAWS Headquarters. Such comments will receive careful consideration by the AW D1 Committee on Structural Weldingand the author of the comments will be informed of the Committee's response to the comments. Guests are invited to at-tend all meetings of the AWS D1 Committee on Structural Welding to express their comments verbally. Procedures forappeal of an adverse decision concerning all such comments are provided in the Rules of Operation of the Technical Ac-tivities Committee. A copy of these Rules can be obtained from the American Welding Society, 8669 NW 36 St, # 130,Miami, FL :2014 DedicationIn MemoriamPaul J. Sullivan1926 2013 This issue of AWS , Structural Welding Code Aluminum ,is dedicated to the memory of Paul J. Sullivan. Among hismany contributions to the American Welding Society, Paul wasone of the charter members of the D1G Aluminum Subcom-mittee.

7 He was a faithful member for many years and served asthe Subcommittee Chairman for six years. Without Paul s wis-dom and guidance, the Code would not be the documentwe have today.

Because of the interest of both the Aluminum association and the AmericanWelding Society, it was decided to begin in the mid-70s the task of developing a Structural Welding code for Aluminum . Ini-tially, the effort was undertaken by a task force of the Aluminum association .
