Non-destructive testing specialists are professionals that use their wide range of technological, reasoning, and creative skills to find imperfections in materials, structures, and equipment. They use older, reliable methods to find and repair these imperfections as well as develop new methods and technology to improve their field.
Non-destructive testing specialists use techniques such as amperage measurement, rheometric flow measurement, voltage measurement, and radio astronomy to detect imperfections that do not meet regulations and laws. Specialists are able to easily interpret the findings gathered by the use of any of these methods, and can detect imperfections on large structures such as trains, airplanes, reactors, dams, bridges, and many others. They write reports that are sent to their clients, explaining their findings in great detail.
Apart from the technical aspects of the job, these specialists are professionals that supervise staff and trainees within their testing field. They use strong communications skills to interact with their superiors and subordinates through many means to ensure the testing project goes smoothly and produces accurate results.

Non-destructive testing specialists inspect structures, equipment, and materials to determine where problems or defects are present. They must be able to gather information from all sources regarding the materials in question. Specialists are responsible for recording and often transcribing information about their studies and findings. This information is used to evaluate and decide whether there are defects in the materials and then to judge whether the proper regulations and standards were followed when building the equipment and structures, or when processing or manufacturing the materials used.
Problem solving is one of the main jobs of non-destructive testing specialists. They must be able to analyze all aspects of the problem or situation and devise a well-organized, effective plan of action to correct the errors. These corrections must meet specific safety laws and regulations. Non-destructive testing specialists are responsible for choosing the best solution out of the many they could select.
Another aspect of the job of a testing specialist is to teach other people to do their jobs safely. Specialists must develop training classes and programs to instruct others based on their educational needs. Specialists can often be considered mentors to their subordinates, teaching them the regulations and high quality skills of analyzing situations and processing information. Communication plays a large role in this position—whether it is talking face to face, by email or letter, or on the phone—as specialists need to convey their findings and the progress of their projects to various stakeholders.
Non-destructive testing specialists spend their hours looking into what makes materials used in a vast number of different areas the same or different from other materials.

They provide a great deal of guidance to their clients as well as their subordinates to ensure the best performance standards are being met.
Non-destructive testing specialists also focus on the repair and upkeep of their testing equipment and other electronic devices related to the job. They use their creative minds to develop new equipment and programs that perpetuate the importance of their careers.
Many positions require a high school diploma or GED certification at the level where the job will place them (for example, level, I, II, or III), experience with various materials, and a background in engineering, aerospace, and related procedures. For entry-level positions, little experience is required, with training provided. For higher-level positions, multiple years of experience with x-ray equipment may be required.
Non-destructive testing specialists must have strong abilities for recognizing where there are potential problems, and they must be able to easily see problems that are already occurring. They must be able to see at a very close range with great precision to detect minute errors that could cause a far larger problematic situation. Specialists must be able to take direction that is given to them verbally and then apply reasoning to the problems they face so as to provide easy to understand answers to questions they are asked.
Excellent vision is required, not only for seeing objects up close, but also to be able to clearly tell the difference between colors, including differences in the shade or brightness of the color. They must be able to see the smallest imperfection.
