Success tips for Successful NDT career
The success of any Nondestructive testing(NDT) methods and procedures depends upon the knowledge, skill, and experience of the NDT personnel involved in the profession. The person(s) responsible for detection, interpretation and Evaluation of indications, such as Ultrasonic testing, Radiographic testing, or Magnetic particle testing, must be qualified and certified to specific industry or other acceptable government or industry standards such as American Society for Non destructive Testing(ASNT) Personnel Qualification and Certification as per SNT-TC-1A or Indian Society for Nondestructive testing(ISNT) for different levels like Level I (1), II (2), III (3)or any other Internationally recognized personnel qualification training and certification. The person should be familiar with the respective NDT inspection test method/s, know the potential types of discontinuities peculiar to the material, and be familiar with their effect on the structural integrity of the part.
Inspection personnel should know where discontinuities occur or can be expected to exist and what effect they can have on the service life of the component or assembly. Misinterpretation and/or improper evaluation of discontinuities or improper performance of inspection tests can result in serviceable parts being rejected and defective parts being accepted. NDT personnel should be familiar with the detection of discontinuities such as: corrosion, inherent discontinuities, primary processing discontinuities, secondary processing or finishing, in-service discontinuities and codes, standards, specifications pertaining to the NDT.
It is with the interest in learning the skills and practicing, one can become a more professional NDT inspector/technician. More than just having the knowledge got in the training courses, it is important to learn the things with patience during NDT inspection and regularly practice the inspection/test methods to understand and develop the skills independently for a successful NDT career.
