Foreword

(This Foreword is not a part of AWS QC2-93, Recommended Practice for the Training, Qualification and Certification of Welding Inspector Specialist and Welding Inspector Assistant, but is included for information purposes

only.)

The purpose of welding inspection is to determine that a welded product meets the requirements of a specific code, standard, specification or contract, These documents usually contain reference to a specific code, standard or specification, and detailed drawings that outline general aad specific requirements for the work The welding inspector must be thoroughly familiar with the welding processes used, welding prccdures, welder qualifications, materials and limitations of weld testing; and must be able to read drawings, keep records, make reports and make responsible judgements

For weld inspection to be effective, it must be performed in a manner thal is consistent with the specification requirements and the technical and ethical principles The employer must accept the burden of responsibility of taining, lesling, qualifying and certifying emplayees in accordance with an estaglished written practice,

Commenls aod suggestions for improvement are welcome They should be sent in writing to the Secretary, AWS Qualification and Ccriification Committee, American Welding Society, 550 N.W LeJeune Road, P.O Box 351040, Miami, FL 33135

Official interpretations of any of the technical requirements of this standard may be obtained by sending a request, in writing, t the Director of Qualification and Certification Department, American Welding Society A formal replay will

be issued after it has been reviewed by the appropriate porsonne] faltowimg established procedures
