7、hods, 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, documen

8、ts that are included in federal or state laws and regulations, or the regulations of other govern-mental bodies, their provisions carry the full legal authority of the statute. In such cases, any changes in those AWSstandards must be approved by the governmental body having statutory jurisdiction be

9、fore they can become a part ofthose laws and regulations. In all cases, these standards carry the full legal authority of the contract or other documentthat invokes the AWS standards. Where this contractual relationship exists, changes in or deviations from requirementsof an AWS standard must be by

10、agreement 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 the AWS administers theprocess and establishes rules to pr

11、omote 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 property, or other damages of any nature whatsoeve

AWS also makes no guarantee or warranty as to the accuracy or completeness of any informationpublished herein.In issuing and making this standard a

Anyone using these documents should rely on his or her own independent judgment or, as approp

14、riate, seek theadvice of a competent professional in determining the exercise of reasonable care in any given circumstances. It isassumed that the use of this standard and its provisions are entrusted to appropriately qualified and competent personnel.This standard may be superseded by the issuance

15、of new editions. Users should ensure that they have the latest edition.Publication of this standard does not authorize infringement of any patent 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 in

16、fringement ofany patent or product trade name resulting from the use of this standard.Finally, the AWS does not monitor, police, or enforce compliance with this standard, nor does it have the power to do so.On occasion, text, tables, or figures are printed incorrectly, constituting errata. Such erra

17、ta, when discovered, are postedon the AWS web page (www.aws.org).Official interpretations of any of the technical requirements of this standard may only be obtained by sending a request, inwriting, to the appropriate technical committee. Such requests should be addressed to the American Welding Soci

LeJeune Road, Miami, FL 33126 (see Annex A).With regard to technical inquiries made concerning AWS standards, oral opinions on AWS standards may be rendered.These opinions are offered solely as a convenience to users of this sta

These individuals donot speak on behalf of AWS, nor do these oral opinions constitute official or unofficial opinions or interpretations ofAWS. In addit

20、ion, oral opinions are informal and should not be used as a substitute for an official interpretation.This standard is subject to revision at any 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 w

21、ithdrawn. Comments (recommenda-tions, additions, or deletions) and any pertinent data that may be of use in improving this standard are requiredand should be addressed to AWS Headquarters. Such comments will receive careful consideration by the AWS D16Committee on Robotic and Automatic Welding and t

22、he author of the comments will be informed of the Committeesresponse to the comments. Guests are invited to attend all meetings of the AWS D16 Committee on Robotic and Auto-matic Welding to express their comments verbally.

ScopeThe purpose of D16.3M/D16.3:2009, Risk AssessmentGuide for Robotic Arc Welding, is to identify and evaluatepotential safety hazards associated with robotic arc weld-ing. It is not intended to be a guidel

36、ine for other roboticapplications. This guide is intended for persons perform-ing risk assessment and applies to arc welding robots androbot arc welding systems performing the gas metal arcwelding (GMAW) or flux cored arc welding (FCAW)process.It is not intended to be a guideline for other robotic a

37、ppli-cations, such as:(1) Automatic guided vehicle systems,(2) Undersea and space robots,(3) Automatic conveyor and shuttle systems,(4) Teleoperators,(5) Mobile robots, and(6) Multiple robots.This standard makes use of both the International Systemof Units (SI) and U.S. Customary Units. The latter a
