Radiograpic Testing Level2

Why attend this course:

This programme is designed for those who have received little or no formal radiographic training. This syllabus has been designed to cover all major aspects of theory and practical radiography for the examination of welds. The syllabus includes hands-on experience relating to the use of X and gamma radiographic techniques and darkroom techniques. Ideal as a pre-examination training package.
