Radiologic Evaluator LPCS

Purpose

To interpret (by use of computer applications) all film and electronically acquired radiographs taken of castings to determine that discrepancies meet customer specifications and PCC standards; to determine if parts are acceptable or need repair, mark and route parts for necessary repairs and sign final reports that approve castings sent to customers.

Preparation: To review specifications and radiographs prior to evaluation.

• Review Technique Cards and paperwork to part specifications.
• Sort radiographs by view for each part.
• Check each radiograph to determine that appropriate quality for image sensitivity and accuracy is obtained.
• Ensure proper image file management protocol is followed.

Interpretation: To interpret and evaluate radiographs in order to determine the quality of castings and to accept the part or route for repair according to customer and PCC specifications.

• Visually evaluate radiographic indications to determine if casting or welding discontinuities exist.
• Interpret identified discontinuities to determine their cause and/or whether they meet customer specifications.
• Interpret and identify surface and subsurface discontinuities per customer specifications.
• Evaluate parts with repeat problem areas; consult with engineering as appropriate.
• Mark problem areas on parts needing repair; may request additional radiographs to further evaluate indications; routes for repair on rework routing cards; may decide on or recommend necessary repairs.
• Sign and stamp reports for acceptance of parts as determined by interpreter.
• Review weld maps to ensure all welds have been radiographed.
• Perform mathematical calculations from detailed drawings or blueprints to determine acceptability.

• May be required to handle hazardous waste and follow all required PPE regulations.
• Must meet all production and quality standards per department standards.
• Accurately record and document work performed.
• Provide training and work direction to less experienced personnel as assigned.
• Perform any function of radiographers, darkroom operators and other department personnel as assigned.

• Must comply with all applicable safety requirements, policies and procedures while maintaining a clean, safe, and orderly work environment. Must participate in required training, medical monitoring, safety and health evaluations and programs.
• Regular and predictable attendance.
• Perform required overtime as directed by supervision.
• Perform other tasks as directed.
