Starting a Career in NDT: A Guide for Beginners and Aspiring NDT QA/QC Inspectors
If you are a fresh graduate or looking for a career change into a field related to quality control in various industries, Non-Destructive Testing (NDT) may be an interesting option for you to consider.

NDT is the process of inspecting materials or workpieces without causing damage, in order to assess the integrity of the structure, safety, and efficiency. It plays an important role in a variety of industries such as aerospace, oil and gas, construction, and manufacturing.
Reasons to Start a Career in NDT:
- High Demand: With increasing demand in every industry, having NDT skills and certifications increases employment opportunities.
- Attractive Income: NDT professionals earn good income and can still grow in their careers
- No Specific Background Required: Even if you did not graduate with an engineering degree, you can start a career in NDT with training and certification.
First Steps to Becoming an NDT Specialist:
Understand the different testing methods.
- VT (Visual Testing): Inspection with the naked eye. Suitable for beginners as it requires minimal equipment.
- PT (Liquid Penetrant Testing): Using a penetrant to detect surface flaws.
- MT (Magnetic Particle Testing): Using magnetic particles to detect flaws in magnetic metals.
- UT (Ultrasonic Testing): Using sound waves to inspect the interior of a workpiece.
- RT (Radiographic Testing): Using radiation to inspect internal structures.
- IR (Infrared Thermography Testing): Using a thermal imaging camera to detect temperature changes in materials or structures. Suitable for inspecting electrical systems, heat pipes, and insulation.
- ET (Eddy Current Testing): Using eddy currents to detect flaws on the surface and below the surface in conductive materials.
Choose the appropriate training and certification. Training is the most important step. Beginners can start with NDT Level 1 courses, which focus on the use of basic equipment. With experience, they can continue to Level 2 or 3.
Training and education centers in Thailand. There are many quality training centers in Thailand that provide training and certification in NDT, such as:
- TIV (Technical Inspection and Verification) (https://www.tiv.co.th/)
- Training centers in universities and specialized institutes.
Certification. Taking exams to obtain certificates such as ASNT SNT-TC-1A Level I or II is important to demonstrate expertise and ability to perform non-destructive testing.
Tips for Starting and Succeeding in an NDT Career:
- Learn the basics and practice your skills continuously.
- Gain more knowledge about the industry you are interested in, such as aviation or energy.
- Join the NDT professional network to exchange knowledge and find advice.
Starting a career in NDT can be a major turning point for you. Whether you are a fresh graduate or changing careers, having the right certifications and skills will open doors to a stable and growing career in the long term.
