8、et: . AWS SENSE QC10:2008 Statement on Use of AWS Standards All standards (codes, specifications, recommended practices, methods, classifications, and guides) of the American Welding Society (AWS) are voluntary consensus standards that have been developed in accordance with the rules of the American

9、 National Standards Institute (ANSI). When AWS standards are either incorporated in, or made part of, documents that are included in federal or state laws and regulations, or the regulations of other governmental bodies, their provisions carry the full legal authority of the statute. In such cases,

10、any changes in those AWS standards must be approved by the 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. Where

11、 this contractual relationship exists, changes in or deviations from requirements of an AWS standard must be by agreement between the contracting parties. This AWS standard was developed through a consensus standards development process that brings together volunteers representing varied viewpoints

12、and interests to achieve consensus. While AWS administers the process and establishes rules to promote fairness in the development of consensus, it does not independently test, evaluate, or verify the accuracy of any information or the soundness of any judgments contained in its standards. AWS discl

13、aims liability for any injury to persons or to property, or other damages of any nature whatsoever, whether special, indirect, consequential or compensatory, directly or indirectly resulting from the publication, use of, or reliance on this standard. AWS also makes no guarantee or warranty as to the

14、 accuracy or completeness of any information published herein. In issuing and making this standard available, AWS is not undertaking to render professional or other services for or on behalf of any person or entity. Nor is AWS undertaking to perform any duty owed by any person or entity to someone e

15、lse. Anyone using these documents should rely on his or her own independent judgment or, as appropriate, seek the advice of a competent professional in determining the exercise of reasonable care in any given circumstances. This standard may be superseded by the issuance of new editions. Users shoul

16、d 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 accept any and all liabilities for infringement of any patent or trade name items. AWS disclaims liability for the infringement of any patent o

17、r product trade name resulting from the use of this standard. On occasion, text, tables, or figures are printed incorrectly, constituting errata. Such errata, when discovered, are posted on the AWS web site (www.aws.org). Official interpretations of any of the technical requirements of this standard

18、 may only be obtained by sending a request, in writing, to the Director of Education, Technical Services Division, American Welding Society, 550 N.W. LeJeune Road, Miami, FL 33126. With regard to technical inquiries made concerning AWS standards, oral opinions on AWS standards may be rendered. Howev

19、er, such opinions represent only the personal opinions of the particular individuals giving them. These individuals do not speak on behalf of AWS, nor do these oral opinions constitute official or unoffi- cial opinions or interpretations of AWS. In addition, oral opinions are informal and should not

20、 be used as a substitute for an official interpretation. This standard is subject to revision at any time by the AWS Committee on Education. Comments (recommendations, ad- ditions, or deletions) and any pertinent data that may be of use in improving this standard are required and should be ad- dress

21、ed to AWS Headquarters. Such comments will receive careful consideration by the AWS Committee on Education and the author of the comments will be informed of the Committees response to the comments. Guests are invited to at- tend all meetings of the AWS Committee on Education to express their commen

22、ts verbally. Procedures for appeal of an adverse decision concerning all such comments are provided in the Rules of Operation of the Education Committee.

27、word This foreword is not a part of QC10:2008, Specification for Qualification and Certification of Level IEntry Welder, but is included for informational purposes only. The AWS Schools Excelling through National Skill Standards Education (SENSE) program began in 1993 with the award of a grant by th

28、e U.S. Department of Education to develop a series of standards and a program for the recognition of welders based on welding performance testing and practical knowledge tests. The development of this National Skill Standard has involved the participation of the welding industry through a survey des

29、igned to determine a consensus of welder skills and competencies required for individuals seeking the development of their welding skills. The result of this industry survey was an occupational task analysis that formed the basis for guidelines for the training of welders at three levels: Level IEnt

30、ry Welder, Level IIAdvanced Welder, and Level IIIExpert Welder. Three specifications were developed in the period July 1993 to July 1996: AWS QC10-95, Specification for Qualification and Certification of Entry Level Welders AWS QC11-96, Specification for Qualification and Certification for Level IIA

31、dvanced Welder AWS QC12-96, Specification for Qualification and Certification for Level IIIExpert Welders In addition, guideline documents were developed for each level: AWS EG2.0-95, Guide for the Training and Qualification of Welding Personnel: Entry Level Welder AWS EG3.0-96, Guide for the Traini

32、ng and Qualification of Welding Personnel: Level IIAdvanced Welder AWS EG4.0-96, Guide for the Training and Qualification of Welding Personnel: Level IIIExpert Welder The present standard is the first in a series of revisions to the SENSE program documents and updates QC10:2004. The administration o

33、f the program has been more clearly defined emphasizing the modular nature of the guidelines and allowing for the recognition of welders who complete defined portions of the program. Your comments for improving the Specification for Qualification and Certification of Level IEntry Welder are welcome.

41、. Scope 1.1 This standard establishes the minimum requirements for qualification and certification as a SENSE Level IEntry Welder with the American Welding Society. 1.2 This standard specifies practical knowledge and performance tests that require a minimum level of reading, computational, and manua

42、l skills to successfully complete. 1.3 All individuals meeting the specified performance criteria at a facility that is a training organization will be listed in the AWS database of SENSE Entry Welders. 1.4 Organizations that are not training organizations may use this standard, but individuals they

43、 instruct will not be listed in the AWS database of SENSE Entry Welders. 1.5 Although a written test including questions on safety is required by this standard, this standard is not intended to address safety and health. Safety and health require- ments are provided in ANSI Z49.1, Safety in Welding,

44、 Cutting, and Allied Processes, other safety and health standards, and federal, state, and local government regu- lations. The responsibility for safety is primarily with the welder, the training organization during training and test- ing, and afterwards, with the employer. 2. Referenced Document 1.
