Radiographic Interpretation

The course satisfies the formal training requirements of ASNT Recommended Practice SNT-TC-1A, BS EN 4179 and NAS-410 and meets the requirement of PCN for the General and Aerospace industry sectors. It covers X and Gamma radiographic interpretation of light and dense metal castings, OR light and dense metal welds, OR aircraft structure as required.

It provides a thorough foundation for technicians, inspectors, and engineers who might be required to interpret radiographs. Additionally it will aid Level I Radiographers progressing to Level II qualification.

Theoretical training is complemented by comprehensive practical interpretation sessions in the relevant industry sector, under the guidance of qualified instructors.

Students are provided with sufficient theoretical and practical tuition to enable them to interpret radiographs against applicable codes and standards. This is on the basis of knowledge of the radiographic principles involved, process technology and the appearance of the images of likely discontinuities, and the relevant contractual requirements.

The course includes, but is not limited to, the following:

Basic principles of X and Gamma Radiography . Safety,
Selection of films, screens, cassettes, and film holders
Density and contrast . Radiation quality and the effects of scatter,
Image quality and the use of IQI's; measurement of sensitivity,
Choice of exposure techniques . Processing and process control,
Artifacts and processing faults . The radiographic workroom and viewing conditions,
Evaluation of radiographic images,
Sentencing of radiographs against applicable codes and standards,
Report writing

Students are assessed for comprehension and progress during the course, via a structured series of both theoretical and practical phase assessments, which facilitate counselling and assistance where required. On request a formal end of course examination can be conducted.

Lunch, refreshments and a full set of course notes will be provided during the course.
