Objective:
Radiographic Film Interpretation - Level II, Classroom NDT training course is developed to meet the requirements of ASNT SNT-TC-1A, CP -189 and other equivalent standards and customer specific written practice for training and certification in this method of Non-Destructive Testing personnel.
After completion of Radiographic Film Interpretation classes, you will get in-depth knowledge of Radiographic Film Interpretation principles, equipment, and application of radiographic techniques and interpretation of radiographic film of various product forms.
Training Examination & Certification Requirement:
During this Radiographic Testing training class, you will give examination in General theory, Specification, and Practical. You are required to successfully pass these three examinations with minimum of 70% grading in each examination and average grading of all three examinations should be 80% minimum as per the requirement of ASNT SNT-TC-1A 2011.
OJT Hours: As per requirements of ASNT SNT-TC-1A, you need to have a minimum of 220 Hours on-job training (OJT) after completion of training classes for certification in this method.
Basic Principle of Radiographic Film Interpretation
Radiography involves the use of penetrating X-ray or gamma radiation to examine the parts and products for imperfections. An X-ray generator or radioactive isotope is used as a source of radiation. Radiation is passed through a specimen onto film or other imaging media. The resulting shadow image shows the dimensional features of the part. Possible imperfections are indicated as density changes on the film in the same manner as medical X-ray shows broken bones.
