About the role
An NDT Technician inspects welds, castings and components for hidden defects without damaging them. They perform non-destructive testing methods such as ultrasonic, radiography, magnetic particle and dye penetrant testing, interpret results against acceptance standards, and record findings. The role is essential in fabrication, engineering and heavy manufacturing where a hidden crack can be dangerous. In an Indian plant or project site the NDT technician holds method certifications, follows safety rules strictly for radiography, and reports accept or reject decisions that keep welds and components safe.
Key responsibilities
- Perform assigned non-destructive tests such as ultrasonic, magnetic particle, dye penetrant and radiography.
- Set up and calibrate NDT equipment and reference blocks before each inspection.
- Interpret indications against the applicable code and acceptance criteria.
- Record test results clearly and mark accepted and rejected areas on the component.
- Raise inspection reports and communicate rejects for repair and re-test.
- Follow radiation safety rules strictly during all radiographic testing work.
- Maintain NDT consumables, films and equipment in working condition.
- Support weld and casting inspection during fabrication and at project sites.
- Keep certification and test records ready for client and third-party review.
- Coordinate re-tests after repair and confirm defects are cleared.
Requirements
- A diploma or ITI in a relevant trade, or a science background
- ASNT Level II certification in the relevant NDT methods
- Radiation safety certification for radiography
- 2 to 6 years in NDT inspection in fabrication or engineering

What does an NDT technician do?
An NDT technician inspects welds, castings and components for hidden defects without damaging them. They perform methods such as ultrasonic, radiography, magnetic particle and dye penetrant testing, interpret results against acceptance codes, and record findings. They mark accepted and rejected areas, follow radiation safety rules, and confirm that repaired defects are cleared on re-test.
What certification does an NDT technician need in India?
An NDT technician usually needs ASNT Level II certification in the methods they perform, such as ultrasonic or radiographic testing. Radiation safety certification is required for radiography. A diploma, ITI or science background is the common education base. Certification matters more than the degree, since clients often require certified technicians.
What is the difference between destructive and non-destructive testing?
Destructive testing breaks or damages a sample to measure properties such as strength, so the tested piece cannot be used. Non-destructive testing inspects a component for defects without harming it, so the actual part stays usable. NDT technicians use non-destructive methods to check welds and castings that must go into service.
