Radiographic Film Interpretation Course
Introduction:
This 5-day course provides basic knowledge into how to effectively interpret radiographs of weldments. Emphasis is placed on the radiographic image quality requirements of codes and specifications. This course is practical in nature, utilizes classroom participation, and allows for hands-on application in the review of radiographic film. The course is designed to provide opportunities for student evaluation of radiographs of pipe and vessel welds. One objective of the course is to produce understanding and confidence on the part of the student/interpreter. However, the primary objective is the enhancement of the student’s ability to make accurate, practical evaluations and decisions when charged with the very important responsibility of film interpretation. This course is designed for the certified level II RT personnel. Various codes and standards are included along with a number of Radiographs containing natural defects. (ASME Sec VIII, API 1104, AWS D 1.1, ASME B 31.3) Radiographic films with natural and artificial discontinuities in welds are being provided for the practical. Detailed acceptance-rejection criteria are being discussed during the class for a thorough understanding of the subject.
