RADIOGRAPHY FILM INTERPRETATION – RTFI LEVEL II TRAINING & CERTIFICATION COURSES
State of Art RT Enclosure, Experienced Trainers & Numerous X-Ray Films for Interpretation Practicals
Radiography testing or X –ray testing is a volumetric NDT method to detect discontinuities and flaws lying inside the materials. RT is widely used in establishing Casting process and Weld joints to evaluate the quality of welds produced. Radiography can be carried out by Gamma Rays using radioactive isotopes such as Iridium 192, Cobalt Co 60, Thulium 170etc or using X –ray equipment produced – cathode ray tube. Gamma Ray Radiography and X-ray radiography are very similar in nature except the way in which radiation is generated. Industrial Gamma Radiography requires radioactive isotopes such as Iridium 192 or Cobalt 60 whereas X-rays are produced by principles used in generating X-rays using equipment or Linear accelerators or Betatrons depending on KV of x-ray and thickness and materials to be radiographed.
One advantage of using Radiography of Castings and Weld joints when compared to Ultrasonic Testing is getting permanent record in the form of Film in Film Radiography and Digital Image in Digital Radiography which can be preserved for the life of the component /structure tested. There are associated safety hazards in usage of Radiography sources. However proper safety procedures must be followed during operation of facility. Atomic Energy Regulatory Board AERB Mumbai India is the authority to control the radiation activities in India. Trinity NDT Radiography facility is licensed from AERB Mumbai India for Radiography Enclosure with Iridium 192 of upto 100 Curie.
Radiography is used in Medical applications since 1885 and later expanded to industrial applications such as RT testing of Critical Weld Joints in Pressure Vessels, Boiler Components, Castings of critical automobile components and engine blocks. Also RT is used in testing assemblies to find the individual components inside assemblies to replicate or reproduce the same indigenously.
Trinity NDT established in 2002 is the fastest growing NDT companies not only in Bangalore but pan India with the presence in more than 40 countries. Radiography facility is NABL ISO/IEC 17025:2017 accredited for Gamma Radiography and X-ray radiography. Gigantic labs are aerospace specialized and equipped with 5 tonne EOT crane facility to carryout the testing of materials of any size. Radiological Safety officers are designated to follow safety regulations issued by the regulatory authorities. Experienced Radiographers, technicians will carry the tests, process the films, interpret and evaluate the films for delivery to the clients ontime.
Industrial Radiography Level I / II training Certification Courses Institute
Radiography testing Level 1 or 2 Certification training courses are crucial for technicians to learn and practice the testing method. Safety concerns are to be addressed appropriately. Each testing course is designed to learn from Basics to Principles of Radiography and safety in Industrial Radiography practice. To operate the camera or IGRED in India the personshall be certified as Industrial Radiography offered by AERB Mumbai. However other aspects of testing such as selection right sources, Techniques, Selection of Films and Penetrameters IQIs, sensitivity, Density of films and Safety in Radiography are taught in depth during this program and practical’s are organized to quickly bring participant to understanding and perform RT testing.
Radiography Film Interpretation RTFI Level 2 Certification training course
Considering safety concerns, majority of graduate mechanical engineers working with various mechanical engineering projects can attend Radiography Interpretation course RTFI level 2 certifications offered by us. The course is designed to give insights into Principles of RT testing, Industrial Applications in Welding and Castings Radiography, Techniques to be followed, Film selection, characteristics of X-ray films, Film density requirements for Industrial Applications, Image Quality Indicators IQI Penetrameter selection, Interpretation and evaluation of Films after processing, sensitivity and contrast requirements.
Practical sessions are part of the training to interpret and evaluate number of films for the quality of technique used and for acceptance of components as per international codes and standards or specifications on Radiography.
