A non-destructive testing inspector determines the safety of structures, vessels, or vehicles using ultrasound, fiber optics, x-ray, or similar equipment. As a non-destructive testing inspector, your responsibilities include testing equipment and hardware, inspecting materials, developing new or adapting existing NDT methods to solve problems, and properly documenting all testing procedures, processes, methods, and results. You use radio astronomy, rheometric flow measurement, and amperage and voltage measurement to evaluate material properties, detect object flaws by making radiographic images, use sonic measurements to map object imperfections, and use a variety of equipment and tools, such as closed circuit television systems or endoscopes to visually examine structures and materials.
