To ensure safety, quality, and performance, NDT professionals need proper training, examination, and certification.

1. NDT Training

NDT training is essential for individuals seeking to become proficient in the different methods of testing. The training generally covers:

Principles of NDT: Introduction to the various NDT techniques (e.g., ultrasonic testing, radiographic testing, magnetic particle testing, dye penetrant testing, eddy current testing, visual inspection, etc.).

Safety Protocols: Understanding the safety measures associated with each technique, especially those that involve radiation or high pressure.

Material Science: Basics of material properties and how they affect test results.

Testing Techniques: Detailed methods for performing tests on different materials and structures.

Interpretation of Results: Analyzing data obtained from NDT methods to make informed decisions about the condition of materials.

2. NDT Examination

After completing training, NDT professionals must pass examinations to validate their knowledge and practical skills. Examinations typically consist of:

Written Exams: Covering theory, principles, and methodologies of various NDT methods.

Practical Exams: Demonstrating the ability to conduct tests correctly, record results, and interpret data.

Oral Exams (in some cases): Discussing real-world scenarios or case studies to test the individual’s problem-solving ability and understanding of NDT practices.

3. NDT Certifications

NDT certifications are offered by accredited organizations, which ensure the competence of professionals to carry out NDT tasks according to established standards. Some well-known certifications include:

a. ASNT (American Society for Nondestructive Testing) Certification:

Level I: Entry-level certification for NDT personnel who perform specific tests under supervision.

Level II: Certification for those who can perform tests independently and interpret results.
