Statement on Use of AWS Standards
AH standards (codes, specifications, recommended practices, methods, classifications, and guides) of the AmericanWelding Society are voluntary consensus standards that have been developed in accordance with the rules of theAmerican National Standards Institute. When AWS standards are either incorporated in, or made part of, documentsthat are included in federal or state laws and regulations, or the regulations of other governmental bodies, theirprovisions carry the full legal authority of the statute. In such cases, any changes in those AWS standards must beapproved by the governmental body having statutory jurisdiction before they can become a part of those laws andregulations. In all cases, these standards cany the full legal authority of the contract or other document that invokes theAWS standards. Where this contractual relationship exists, changes in or deviations from requirements of an AWSstandard must be by agreement between the contracting parties.

(This Foreword is not a part of the Supplement G to AWS QC7-93, Standard for AWS Certified Welders, but isincluded only for information.)
The standard to which this Supplement applies contains the criteria for AWS Certified Welder Program and the AWSNational Registry of Welders. Listing on the AWS National Registry of Welders is at the option of the individualwelder.
This Supplement G should be used in conjunction with AWS QC7-93, Standard for AWS Certification of Welders.This Supplement is not a standard unto itself and shall be considered only as a supplementary part of AWS QC7-93.
This Supplement G specifies requirements intended to provide an alternative ioi manufacturers and contractors tocertify welders. Manufacturers or contractors may continue to conduct their own welder qualification programs as theyhave in the past, unless otherwise defined in contract documents.
Comments and suggestions for the improvement of this standard are welcome. They should be sent to the Secretary,Qualification and Certification Committee, American Welding Society, 550 N.W. LeJeune Road, P.O. Box 351040,Miami, Florida 33135.
Official interpretations of any of the technical requirements of this standard may be obtained by sending a request, inwriting, to the Director of Qualification and Certification Department, American Welding Society. A formal reply willbe issued after it has been reviewed by the appropriate personnel following established procedures.
