How Do You Become NDT Certified?

Becoming NDT (Nondestructive Testing) certified is a structured process that involves gaining education, relevant experience, and passing a certification exam. NDT is crucial for evaluating materials and structures for flaws without causing damage, and it requires specialized knowledge. Here's how to get NDT certified:

1. Understand the NDT Methods

NDT involves several testing methods, including:

• Ultrasonic Testing (UT)
• Magnetic Particle Testing (MT)
• Penetrant Testing (PT)
• Radiographic Testing (RT)
• Visual Testing (VT)

2. Educational Requirements

To become NDT certified, you generally need a minimum educational background:

• High School Graduate
• Engineering Degree (e.g., Mechanical or Civil Engineering)

3. Gain Relevant Experience

Before you can be certified, you need to gain hands-on experience as an NDT trainee. The length of experience required varies by certification level:

• Level I (Entry Level) requires supervised work in basic operations.
• Level II (Intermediate Level) allows for more independent work and responsibilities.
• Level III (Expert Level) involves oversight of other NDT personnel and advanced interpretations.

4. Meet Eye Fitness Requirements

Candidates must pass certain vision tests, such as near-vision acuity and color vision, to ensure they can accurately assess materials.

5. Undergo Training

You need to complete specific training in your chosen NDT methods. Training can be done through:

• In-house programs (with Level III professionals providing the training)
• External NDT agencies offering professional training services.

Training typically includes both classroom instruction and practical hands-on sessions.

6. Certification Exams

After completing training, you must pass a written and practical exam to demonstrate your understanding of NDT methods and ability to interpret results.

7. Certification Programs

There are different certification programs depending on the standard followed:

• ASNT (American Society for Nondestructive Testing) SNT TC 1A: This is one of the most widely recognized certification programs, where employers certify employees through an internal process based on their written practices.
• ISO 9712:2012: This international standard certifies NDT personnel in various industries and NDT methods.
• Other Schemes: Sector-specific certifications such as NAS410/EN4179 for aerospace applications.

8. Maintain Certification

NDT certifications typically need to be renewed after a certain period, which often requires continuing education and proof of ongoing experience.

Key Steps to Get Certified as per ASNT SNT TC 1A:

1.    Meet Educational and Experience Requirements.

2.    Complete Training for the Method(s) (e.g., UT, MT, PT, etc.).

3.    Pass the Certification Exam.

4.    Receive Certification at Level I, II, or III.

Additional Resources:

• MWIP: Offers training and certification services aligned with ISO 9712 and ASNT standards.
• Training Centers: Specialized organizations offer NDT training, including TWI (The Welding Institute), which helps with international certifications.

By following these steps, you'll be on the path to becoming an NDT-certified professional, ensuring that you have the skills and knowledge to assess materials and components for safety and quality.
