7、rdsAll 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 National Standards Institute (ANSI). When AWS American N

8、ational 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, any changes in those AWS standards must

9、 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 this contractual relationship exists,

10、changes in or deviations from requirements of an AWS standard must be by agreement between the contracting parties.AWS American National Standards are developed through a consensus standards development process that brings together volunteers representing varied viewpoints and interests to achieve c

11、onsensus. 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 disclaims liability for any inju

18、 requirements of this standard may only be obtained by sending a request, in writing, to the appropriate technical committee. Such requests should be addressed to the American Welding Society, Attention: Managing Director, Technical Services Division, 8669 NW 36th St, #130, Miami, FL 33166 (see Anne

27、:2015viiForewordThis foreword is not part of AWS C1.5:2015, Specification for the Qualification of Resistance Welding Technicians, but is included for informational purposes only.This specification for the qualification of resistance welding technicians was developed to provide a qualification basis

28、, which defines minimum requirements for a resistance welding technician to demonstrate competence through a combination of education, experience, and examination.The resistance welding technician (RWT) is a person who is responsible for maintaining resistance welding equipment, troubleshooting resi

29、stance welding problems, and providing advice on the application of the resistance welding process. The RWT shall be familiar with various resistance welding processes, specifications, basic electrical and mechanical principles, resistance welding equipment, inspection methods, acceptance criteria,

30、tests, welding qualification requirements, and other aspects of fabrication and assembly.For the welding technicians to be effective, the activities they perform must be consistent with specified requirements, technical, and ethical principles. The RWT may also produce reports aimed at optimizing co

31、st, quality, and productivity. The RWT should be able to work with management representatives, inspection personnel, welders, and support crafts, and should be able to understand the role of each in the development of quality welds.All revisions to the 2009 edition are identified by a vertical line

32、in the margin adjacent to the text.Comments and suggestions for the improvement of this standard are welcome. They should be sent to the Secretary, AWS C1 Committee on Resistance Welding, American Welding Society, 8669 NW 36th St, #130, Miami, FL 33166.AWS C1.5:2015viiiThis page is intentionally bla

General Requirements1.1 Scope. This specification establishes qualification requirements

36、for a resistance welding technician (RWT). It describes how qualifications are determined, and the practice by which qualification may be attained and maintained. The user of this specification will evaluate the qualifications of each candidate, and provide examinations to test the candidates resist

37、ance welding skills and knowledge, as well as, his or her ability to apply the principles of resistance welding.This specification is intended to supplement the minimum requirements of employers, codes, other standards, or documents, and shall not be construed as a preemption of the employers respon

38、sibility for the work or for the performance of the work. Resistance welding processes include spot welding, projection welding, seam welding, butt welding, flash welding, micro joining, resistance brazing, resistance soldering and resistance heating. It is understood not all of these disciplines ar

39、e used in every situation and it shall be the responsibility of employers to determine their employee, who having qualified as a RWT, is capable of performing the specific duties involved in their career assignments.While the RWT has established excellent credentials, qualification to this specifica

40、tion alone may not legally qualify the technician to provide technical services to the public. Contract documents and building or jurisdiction laws may require technical services to be performed under the direction and responsibility of others such as a registered Professional Engineer (P.E.). The R

41、WT designation DOES NOT imply the status of a registered P.E. under the laws of any state or other governmental entity.As used in this specification, the word shall denotes a requirement, the word should denotes a guideline, and the word may denotes a choice.1.2 Units of Measurement. This standard d

42、oes not require units of measure. Therefore, no equivalents or conversions are contained except when they are cited in examples.1.3 Safety. Safety and health issues and concerns are beyond the scope of this standard, and therefore are not fully addressed herein.Safety and health information is avail

This standard does not purport

45、to address all safety and health risks that may be encountered. The user of this standard should establish an appropriate safety program to address such risks as well as to meet applicable regulatory requirements.
