2、ities and Certified WeldersUnder the Direction of theAWS Certification CommitteeApproved by theAWS Board of DirectorsAbstractThis specification describes a program administrated by the American Welding Society (AWS) for accreditation of testfacilities used to perform welder qualification and testing

3、 for the certification of welders. The AWS Certified WelderProgram provides a means for the transference of welder qualifications from employer to employer without retesting.This specification defines the minimum requirements for welder participation in the program and the methods to be usedby emplo

7、l standards (codes, specifications, recommended practices, methods, classifications, and guides) of the AmericanWelding Society (AWS) are voluntary consensus standards that are developed through a consensus standards develop-ment process that brings together volunteers representing varied viewpoints

8、 and interests to achieve consensus. While theAmerican Welding Society administers the process and establishes rules to promote fairness in the development of con-sensus, it does not independently test, evaluate, or verify the accuracy of any information or the soundness of any judg-ments contained

9、in its standards. Further, given the rapid changes in the field, AWS cannot warrant that the certificationstandard will at all times reflect the most current knowledge.Certification is achieved by satisfying a combination of defined education, experience, and/or examination requirements.Certificatio

10、n is not an assurance of future competence or ability.An endorsement to a certification adds to a certification by indicating demonstration of a knowledge, skill, or ability in aparticular skill area that may not be sufficiently broad or unique to support a separate and distinct certification design

11、ation.An endorsement is not an indication of approval by AWS or an assurance of future performance.AWS disclaims liability for any injury to persons or to property, or other damages of any nature whatsoever, includingspecial, indirect, consequential, or compensatory damages, directly or indirectly r

12、esulting from the negligent conduct orother acts or omissions of any individual certified by AWS.In issuing and making this standard available, AWS is neither undertaking to render professional or other services for oron behalf of any person or entity, nor is AWS undertaking to perform duty owed by

13、any person or entity to someone else.Employers and other persons utilizing the services of individuals certified by AWS are responsible for determining thequalifications, competence, and ability of those individuals.This standard may be superseded by new editions. This standard may also be corrected

14、 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 is posted on the AWS web page (www.aws.org). Users should ensure that they havethe latest edition, amendments, erra

15、ta, 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 disclaims liability for the infringement of anypatent or product trade name resulting

16、 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 errata, when discovered, are postedon the AWS web page (www

17、.aws.org).Official interpretations of any of the technical requirements of this standard may only be obtained by sending a request,in writing, to the appropriate certification committee. Such requests should be addressed to the American WeldingSociety, Attention: Managing Director, Certification Dep

Comments (recommendations,additions, or deletions) and any pertinent data that may be of use in improving this standard are required and should beaddressed to AWS He

21、adquarters. Such comments will receive careful consideration by the AWS Certification Committeeand the author of the comments will be informed of the Committees response to the comments. Guests are invited toattend all meetings of the AWS Certification Committee to express their comments verbally. P
