35、h all sections of this standard.1.2 In the certification process, AWS conducts an examination to determine a persons generalknowledge of robotic arc welding operation and related technical areas. No determination ismade of an individuals capabilities in applying that knowledge neither within a speci

36、fic workenvironment nor under actual working conditions.1.3 In the certification process, the employer is responsible for determining that a person hasother qualifications as stated herein.1.4 It shall be the responsibility of the employers to determine that the CRAW Technician orOperator is capable

37、 of performing the duties involved in their particular welding environment,and to provide or make available such training or indoctrination as may be required.1.5 This standard is intended to supplement the requirements of an employer, code, or otherdocuments and shall not be construed as a preempti

Levels of CertificationThere are two levels of A

45、WS certification, the first level combines AWS D16.4 qualificationlevels 2 and 3 and is titled, Certified Robotic Arc Welding Operator (CRAW Operator). The nextlevel is for AWS D16.4 qualification level 4 and is titled Certified Robotic Arc WeldingTechnician (CRAW Technician).The qualification level

46、 1 from AWS D16.4 is not addressed in this certification document. If anemployer wishes to recognize this level of qualification they can develop their own program butit must not be construed as an AWS certification program.4.
