8、 consensus standards that have been developed in accordance with the rules of theAmerican National Standards Institute (ANSI). When AWS American National Standards are either incorporated in, ormade part of, documents that are included in federal or state laws and regulations, or the regulations of
9、other govern-mental bodies, their provisions carry the full legal authority of the statute.

26、he Qualification and Certification Committee of the American Welding Society was formed in 1973. AWS QC1, Stan-dard for Certification of AWS Welding Inspectors, was first published in 1975. The first examinations for the certificationof AWS Certified Welding Inspector were conducted in the spring an
27、d fall of 1976. Over 30,000 individuals have met therequirements of AWS QC1, worldwide, since the start of the program.

The SWIor WI shall maintain the responsibility for determining if welded assemblies conform to workmanship and acceptancecriteria.4.1.2 WI. The WI shall be able to supervise and train AWIs. The WI shall
37、 be able to perform inspections to applicableprocedures and processes. The WI shall be able to conduct audits of suppliers and organizations providing materials orservices to the project.

The SWI shall be able to perform inspections, supervise one or more WIs or AWIs, write welding proce-dure specifications, test and qualify welders, prepare inspection reports, and review and interpret joining procedures.4.2 Capabilities.
39、 As specified by qualification level, the welding inspector shall, at a minimum, be able to perform thetasks listed in Table 1. This table does not restrict inspectors from performing tasks above their qualification level if theiremployer determines the inspector has the necessary skills to perform
