19、ation purposes only).This standard extends the work of the American Welding Society to further define a national skill standard forthe Level II - Advanced Welder. The American Welding Society was awarded Grant #V244B30006-95 for$1,059,626 by the U.S. Department of Education to develop standards and

20、a certification program for weldersduring the period from July 1993 to July 1996. The total program cost is $2,132,094, of which 49.7%($1,072,468) is an in-kind contribution by AWS.To accomplish its goals, AWS organized an Education Grant Committee, which has representatives from allsegments of the

21、welding industry, including labor organizations and educational institutions. This Committee hasoverseen the efforts toward a standard for the qualification and certification of the Level II - Advanced Welder.The development of this National Skill Standard has involved the participation of the weldi

22、ng industry througha survey designed to determine a consensus of welder skills and competencies required for individuals seekingto continue the development of their welding skills.The results of this industry survey were an occupational task analysis that formed the basis for curriculumguidelines to

23、 guide the training of the Level II - Advanced Welder candidate.This standard defines the requirements for the certification of such individuals and their entry into the NationalRegistry of Level II - Advanced Welders.Comments and suggestions for improvement of this standard are welcome. They should

24、 be sent in writing tothe Secretary, AWS Certification Committee, American Welding Society, 550 N.W.

Scope1.1 This standard establishes the minimum requirements for an organization to participatewith the American Welding

29、Society (AWS) in the qualification and certification ofadvanced welders.1.2 This standard specifies practical knowledge and performance tests that require a moredetailed level of reading, computational, and manual skills to successfully complete.1.3 All individuals that meet the specified performanc

30、e at a facility meeting 3.Requirements for Participating Organizations will be listed in The National Registry ofLevel II - Advanced Welders at the American Welding Society.1.4 Organizations not meeting 3. Requirements for Participating Organizations mayuse this standard, but individuals they certif

31、y will not be listed in the National Registry ofLevel II - Advanced Welders.1.5 Although a written test including questions on safety is required by this standard, thisstandard is not intended to address safety and health. Safety and health requirements areprovided in ANSI Z49.1, Safety in Welding a

32、nd Cutting, other safety and health standards,and federal, state, and local government regulations. The responsibility for safety of theLevel II - Advanced Welder is primarily with the welder, the Participating Organizationduring training and testing, and afterwards, with the employer.1.6 The requir

33、ements of this standard shall not supersede the authority of the trainingfacility as established by the local evaluation guidelines.2.
