6、g Society StandardsAll standards (codes, specifications, recommended practices, methods, classifications, and guides) of the AmericanWelding Society are voluntary consensus standards that have been developed in accordance with the rules of theAmerican National Standards Institute. When AWS standards
7、 are either incorporated in, or made part of, documents thatare included in federal or state laws and regulations, or the regulations of other governmental bodies, their provisionscarry the full legal authority of the statute. In such cases, any changes in those AWS standards must be approved by the
8、governmental body having statutory jurisdiction before they can become a part of those laws and regulations. In all cases,these standards carry the full legal authority of the contract or other document that invokes the AWS standards. Wherethis contractual relationship exists, changes in or deviatio
9、ns from requirements of an AWS standard must be by agree-ment between the contracting parties.AWS American National Standards are developed through a consensus standards development process that bringstogether volunteers representing varied viewpoints and interests to achieve consensus. While AWS ad
10、ministers 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 soundness of any judgments contained in its standards.AWS disclaims liability for any injury to persons or to pr

It is assumed that theuse of this standard and its provisions are entrusted to appropriately qualified and competent personnel.This
14、 standard may be superseded by new editions. This standard may also be corrected through publication of amend-ments or errata, or supplemented by publication of addenda. Information on the latest editions of AWS standards includ-ing amendments, errata, and addenda are posted on the AWS web page (www
15、.aws.org). Users should ensure that theyhave the latest edition, amendments, errata, and addenda.Publication of this standard does not authorize infringement of any patent or trade name. Users of this standard accept anyand all liabilities for infringement of any patent or trade name items. AWS disc
16、laims liability for the infringement of anypatent or product trade name resulting from the use of this standard.AWS does not monitor, police, or enforce compliance with this standard, nor does it have the power to do so.Official interpretations of any of the technical requirements of this standard m
17、ay 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, 8669 NW 36 St, # 130, Miami, FL 33166 (see Annex B).With regard to technical inqui
18、ries 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 them
19、. 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 any
20、time by the AWS D16 Committee on Robotic and Automatic Welding. It mustbe reviewed 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
21、should beaddressed to AWS Headquarters. Such comments will receive careful consideration by the AWS D16 Committee onRobotic and Automatic Welding 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 D16 Commit
22、tee on Robotic and Automatic Welding toexpress their comments verbally. Procedures for appeal of an adverse decision concerning all such comments are pro-vided in the Rules of Operation of the Technical Activities Committee.
