NDT TRAINING IN CHENNAI - ASNT CERTIFICATION

NDT TRAINING AND CERTIFICATION

 
 

1. ULTRASONIC TESTING

 

Training & Certification Course in NDT

 
We are providing Level I and Level II Training and Certification as per Recommended Practice SNT - TC-1A 2006 in the following NDT Method.
 
In Ultrasonic Testing high-frequency sound waves, created by a vibrated crystal in probe, are transmitted into a material to detect imperfections or to locate changes in material properties. The most commonly used ultrasonic testing technique is pulse echo, whereby sound is introduced into a test object and reflections (echoes) from internal imperfections or the part's geometrical surfaces are returned to a receiver.
 
This method is very sensitive to detect crack type defects but requires extensive training for operator to interpret the result.

4. RADIOGRAPHIC TESTING

Training & Certification Course in NDT

We are providing Level I and Level II Training and Certification as per Recommended Practice SNT - TC-1A 2006 in the following NDT Method

RT involves the use of penetrating gamma- or X-radiation to examine materials and product's defects and internal features. An X-ray machine or radioactive isotope is used as a source of radiation. Radiation is directed through a part and onto film or other media. The resulting shadowgraph shows the internal features and soundness of the part. Material thickness and density changes are indicated as lighter or darker areas on the film. The darker areas in the radiograph below represent internal voids in the component. RT is a common method to be used in general metal fabrication and construction. However, there are some limitations of the methods:

  • Extensive safety requirements when the technique relates to radiation exposure.
  • Difficult application to different shapes of testing objects.
  • Long and complicated process required from starting to the end of the work.
