7、at have been developed in accordance with the rules of the American 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 provis

8、ions carry the full legal authority of the statute. In such cases, 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 t

9、he contract or other document that invokes the AWS standards. Where 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 proc

10、ess that brings together volunteers representing varied viewpoints 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 t

11、he 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 whatsoever, whether special, indirect, consequential or compensatory, directly or indirectly resulting from the publication, use of, or reliance

LeJeune Road, Miami, FL 33126. With regard to technical inquiries made concerning AW

17、S standards, oral opinions on AWS standards may be rendered. However, 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 interpretati

The American Welding Society (AWS), recognizing the need for competent welders, through

26、 a grant by the U.S. Department of Education, formed the Education Grant Committee in 1992 and assigned them the task of preparing the initial guide. Welding has become a very sophisticated and technical science, requiring not only mental application but also hands-on abilities. The future need for

27、competent welders should prompt the establishment of a greater number of educational programs. Thus, it becomes imperative that training adequately prepares individuals for industrial assignments at various levels of skill development. To this end the Level IEntry Welder needs to enter the workforce

28、 possessing a prerequisite amount of knowledge, attitude, skills and habits required to perform routine, predictable, repetitive, and procedural tasks involving motor skills, and limited theoretical knowledge while working under close supervision. As the name implies, it is the intent of this Guide

29、to establish, expand, or enhance a private or public training program for Level IEntry Welder. The guidelines contained in this document are based on AWS QC10: Specification for the Qualification and Certification of Level IEntry Welder. AWS QC10 and EG2.0 were developed according to the DACUM metho

30、d, and are based on the results of a national survey to identify requisite entry welder skills and knowledge. Survey participants included individuals from a wide range of business, industrial and educational areas. Therefore, this document represents the AWS Education Grant Committees consensus on

31、the minimum requirements for a Level IEntry Welder as specified by industry, and establishes the guidelines necessary to standardize the training and qualification of Level IEntry Welder on a national basis. Comments and suggestions for the improvement of this standard are welcome. They should be se
