Marietta, Georgia

TECHNICAL AND OFFICE JOB DESCRIPTION

INDUSTRIAL RADIOGRAPHER

Code: 780-3, LG: 15


Occupational Summary

This occupation requires the set-up and use of X-ray equipment and radioisotopes to produce radiographs of major aircraft structures, systems and components thereof and the interpretation of these radiographs to detect unacceptable parts and materials.

Work Performed

Sets up and uses X-ray equipment and radioisotopes to perform radiographic testing, working from charts, handbooks and radiograph log books.

Determines number of views and correct angles at which radiographs of subject should be taken to produce satisfactory images, positioning parts, materials and equipment. Determines exposure time, source-to-film distance, voltage and amperage, radiation intensity and/or shielding, if required, by inserting known information or constants in appropriate basic formula and solving arithmetically for unknown.

Selects and loads photographic plates and intensifying screens and places radioactive materials in position using magnetic handling rods or appropriate remote control equipment. Makes radiographs of aircraft parts and materials such as structural and functional units, landing gear assemblies, castings, forgings, welded and machined parts and assemblies, plastic and other non-metallic parts.

Takes radioactive material and other necessary equipment into assembly and flight line areas and other similar locations, and mounts equipment as necessary to radiograph major sections of such aircraft. May be required to set up and use radioactive materials outside Company plant to make and interpret radiographs of aircraft parts and materials at customer facilities.

Interprets radiographs to detect and identify such defects as cracks, blow holes, porosity, incomplete fusion, inclusions, segregation, cavities, under cuts, and draws. Stamps or otherwise approves acceptable items; rejects unacceptable items and prepares necessary documentation indicating reason for rejection. Contacts engineering, purchasing, and other affected departments to obtain or furnish information.

Performs such incidental duties as mixing developing solutions; developing films in accordance with established procedures; recording exposure time, amperage, voltage, distances and similar information in radiograph log books as reference material; and maintaining files of films.

Knowledge and Ability Required

Knowledge of industrial radiograph techniques and applicable inspection standards and procedures; of gamma ray and X-ray penetration characteristics of aircraft parts and materials. Ability to set up and use X-ray equipment, radioisotopes, and related radiographic equipment; interpret radiographs to determine acceptability of aircraft parts and materials; use detail and assembly blueprints, tool orders, prints, and sketches for reference purposes. Must possess valid X-ray and radioisotopes certificates as required.
