ASNT NDT Level II in Time of Flight Diffraction (TOFD)
ASNT NDT Level II in Time of Flight Diffraction Testing in India
TOFD is based on the principle of using ultrasonic waves to measure the time taken for sound waves to travel through a material and reflect back from defects or boundaries. This provides valuable information about the size, shape, and location of defects within the material.
To become ASNT NDT Level II certified in TOFD, an individual typically needs to follow a process similar to other NDT methods:
- Education and Training: Obtain the necessary education and training in TOFD. This could involve attending formal courses, workshops, or training programs that cover the theory and practical aspects of TOFD.
- Experience: Gain practical experience in performing TOFD inspections under the guidance of a certified Level III professional. The exact number of hours or experience required may vary based on ASNT’s requirements.
- Examinations: Pass both a written examination and a practical examination for TOFD. The written exam tests your theoretical knowledge of TOFD principles, techniques, and procedures. The practical exam assesses your ability to perform actual TOFD inspections and interpret the results accurately.
- Certification: Upon successfully completing the education, experience, and examination requirements, you will be awarded the ASNT NDT Level II certification in TOFD. This certification demonstrates your competence in using TOFD for nondestructive testing.
