Learn RTFI Course at Our Radiography Testing Labs

Radiography X ray testing

The best place to learn film interpretation is radiography testing lab. Unless, the person understands the reasons behind good radiography testing, he/she can never able to interpret properly. This needs, interpreting numerous films on daily basis. Ideal place for learning film interpretation is where RT testing is available. Institutes without such testing labs cannot provide quality training. Trinity NDT is located at Peenya Industrial Area, Bangalore in India. Labs are NABL accredited for Radiography x-ray testing. Serving over 1500+ customers on both X-ray and Gamma ray using Iridium 192 source in the state of Karnataka.

In addition, film processing dark room can enhance you imagination about how the films are processed. The center also has dedicated film processing lab for developing radiographs. Trainers are RSO Level II from AERB and ASNT Level III certified.


About Radiography Film Interpretation Training

Considering safety concerns, engineers working in quality can attend Radiography Interpretation course RTFI level 2. This is certification course organized at Bangalore India as per ASNT SNT TC 1A and ISO9712. The course is designed to give insights into principles of RT testing, Industrial applications in welding, casting, techniques, film selection, characteristics of X-ray films, film density requirements. 

Prior to  interpretation, the course also teaches about Image Quality Indicators (IQI) selection, Interpretation, evaluation of films for quality. Artifacts, false indications. Finally, evaluating for flaws in castings and welds as per ASME, AWS, ISO codes.

Practical sessions are part of the training. Includes demonstration on SWSI, DWSI, DWDI techniques. Read, download RTFI course brochure.

Back to Basics. Radiography Testing.

Radiography Film Interpretation RTFI Course

Radiography testing is a volumetric NDT method to detect flaws lying inside the materials. Widely used in establishing casting process and welds to evaluate the quality of welds produced. Testing is carried out by Gamma Rays using radioactive isotopes such as Iridium 192, Cobalt Co60, Thulium 170 or using X –ray equipment. Both gamma radiography and X-ray radiography are similar in nature except the way in which radiation is generated.

X-rays were discovered in 1895 by Wilhelm Conrad Roentgen (1845-1923) who was a Professor at Wuerzburg University in Germany. Working with a cathode-ray tube in his laboratory, Roentgen observed a fluorescent glow of crystals on a table near his tube. 

The history of radiographic testing (RT) actually involves two beginnings.

1. The first, commenced with the discovery of x-rays by Wilhelm Conrad Roentgen in 1895

2. The second with the announcement by Marie and Pierre Curie, in December of 1898, that they had demonstrated the existence of a new
radioactive material called ‘radium’.

Though medical radiography looks similar, Industrial Gamma Radiography requires radioactive isotopes such as Iridium 192 or Cobalt 60.  However, X rays are produced by principles used in generating X-rays using equipment or Linear accelerators or Betatrons depending on thickness and type of material.

Advantages of RT testing Over UT Testing

One major advantage of Radiography when compared to Ultrasonic Testing is permanent record. In Film Radiography as film, whereas, in Digital Radiography as image. Preserved for the complete life cycle of the component/structure.

There are safety hazards associated with Radiography sources. Round the clock surveillance is needed for radiography. Persons performing RT shall be certified from AERB, Government of India. UT does not require this except the inspector to be certified.

In general, UT testing is effective for higher thickness components due to dead zone limitations. Radiography effective for thinner materials. For example, Ir-192 suitable up to 75mm thickness of steel. Cobalt 60 for 150mm thickness of steel approximately. Thulium 170 can be used up to 10mm of steel only.

Also RT is used in testing assemblies to find the individual components inside assemblies to replicate or reproduce the same indigenously. UT cannot be applied for assembled components. Also needs couplant.

Atomic Energy Regulatory Board AERB Mumbai India is the regulatory authority for radiation activities in India. Trinity NDT Radiography

About Our Radiography Testing Level II Course

Radiography testing Level 1 or 2 Certification training courses are crucial for technicians to learn and practice RT 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.

However in India, to operate the RT testing camera or IGRED in India the person shall be certified as Industrial Radiography offered by AERB Mumbai. However other aspects of testing such as selection right sources, RT 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.
