This introduction to radiographic testing (rt) explains the physics of radiographs, how the devices work, how to read radiographic films, and the terminology used by radiographers, building practical ndt skills.
Explore radiographic testing principles, introduction to radiographs, and techniques for single, double, and panoramic image inspections. Learn film quality, processing, and emerging ideograph models for inspection workflows.
Learn the principles of radiographic testing using x-ray and gamma-ray methods, including film radiographs, defect detection in surfaces and interiors, and the advantages, limitations, and safety considerations.
Explore radiographic testing principles for part 1, including a comparison of x-ray and gamma-ray radiography. See how the radiation source, film, and density differences reveal weld defects and material contrasts.
Explore radiation safety in radiographic testing, detailing ionizing X-ray and gamma rays, dose concepts, occupational exposure limits, and the time, distance, and shielding triangle to protect workers.
Explore radiographic testing techniques for piping—single and double image methods, panoramic and elliptical exposures, source positions, exposure arrangements, and defect visualization.
Explore imaging modalities in radiographic testing, including radiographic film, silver bromide development, digital and computer radiography, and computed tomography with three dimension imaging and real-time inspection.
Explore film radiography principles, including silver halide emulsions, double-layer speed, and the develop and fix process from exposure to latent image and black metallic silver.
Understand film radiography basics: a polyester-based film with gelatin silver halide emulsion sits between the intensifying screen and protective coating; latent images become manifest after processing.
Explore film processing in radiographic testing, detailing manual and automatic processing, development steps, solution ratios, temperatures (18–24 Celsius), times (5–8 min), washing, fixing, drying, and steps to prevent radiographic imperfections.
Apply geometric controls, exposure, and processing to maximize image detail in radiographic testing. Learn how contrast, definition, subject absorption, and motion shape image quality.
Develop skills in radiographic film interpretation by mastering detection, interpretation, and evaluation; optimize viewing through proper darkroom lighting, optical acuity, and correct handling to reliably identify cracks or porosity.
Understanding the physical principles of Radiographic, Testing Learning how the Radiography Testing devices work, you will learn the basics of Radiographic inspection, you will learn how to read the radiographic film and detect the welding defect, you will get familiar with the terminology in Radiographic inspection. Getting ready to pass the Radiography Testing Level 1 Examination for ANST or TWI, to have the practical skills of Radiography Testing required for a Level I (1) technician, Non-Destructive Testing of welding, metal, and machines like Radiography Testing, you will be able to follow practical demonstrations in the radiographic test.
This course is for Beginner RT technicians, Engineer & QA/QC persons, University and College Students looking for a career in the NDT field, Technicians of other NDT methods seeking to advance their career by learning a new NDT method. All people are interested in the material inspection, Students will be able to apply NDT Techniques in Real life.
This course teaches you how to perform radiographic inspections from the beginning to the middle level, Radiographic testing (RT) is one of the Non-Destructive Testing (NDT), Non-Destructive Testing (NDT) is the process of inspecting, testing, or evaluating materials, components or assemblies for discontinuities, or differences in characteristics without destroying the serviceability of the part or system. In other words, when the inspection or test is completed, the part can still be used, in contrast to NDT, other tests are destructive in nature and are therefore done on a limited number of samples ("lot sampling"), rather than on the materials, components or assemblies actually being put into service.
