What is NDT?

NDT or NON Destructive Testing is used to inspect a material to find out defects without destroying the material. Anon-destructive test has the destinct advantage of leaving the test subject intact. As well as the obvious benefits this entails, it also allows for testing of multiple possible problems causes.

what can be found out by NDT?

By destructive testing, physical properties such as Tensile strength, Compressive strength, Impact Strength etc. Can be found out, but the specimen needs to be destroyed. This leads to huge cost in Testing and development. Thus the cost of Quality increases and hence the price of the product too.

Assume that a small scale casting industry produces approximately 100 casting per day. The physical properties can be found out by taking a sample and preparing a specimen from it. The specimen then can be subjected to destructive testing. The results are used to judge the properties of the other 99 samples. If the sample fails in the test, the whole lot is rejected. Also selection of samples leads to high level of sampling errors. By Non-Destructive Testing all the 100 casting can be checked without destroying any, and to find the harmful defects. The Technology of the NDT has improved so much that it is used to find physical properties such as hardness, elasticity etc. NDT finds its usage in industries such as Oil & Gas, Power, Marine, Nuclear, Structural, offshore structures, Defence, Manufacturing, Medical, Aircraft, etc.

What is Quality Assurance and Quality Control?

Quality Assurance (QA) is the process of verifying or determining whether products or services meet or exceed customer expectations. Quality assurance is a process-driven approach with specific steps to help define and attain goals. This process considers design, development, production and service.

Quality Control (QC) is system of routine technical activities, to measure and control the quality of the inventory as it is being developed. The QC system is designed to

  • (i) Provide routine and consistent checks to ensure data integrity, correctness, and completeness.
  • (ii) Identify and address errors and omissions.
  • (iii) Document and archive inventory material and record all QC activities.

What are the type of NDT?

As per the ASNT (American Society of Non destructive Testing) there are 11 methods of NDT of training & certification.

There are:

  • Ultrasonic Testing
  • Radiography Testing
  • Penetarent Testing
  • Magnetic Testing
  • Visual Testing
  • Eddy Current Testing
  • Acoustic Emission Testing
  • Leak Testing
  • Infrared/Thermography
  • Vibration Analysis
  • Neutron Radiography

Who can take the NDT courses?

Engineers, Diploma holders, Degree holders (both Art & Science) ITI holders, +2 & SSLC qualified candidates can appear for the NDT Level-I & Level-II courses. Engineering Diploma & Degree students in their 2nd year & 3rd year of graduation can also attend these courses.
