TITLE(s): NONDESTRUCTIVE TESTER (profess. & kin.)
Conducts radiographic, penetrant, ultrasonic, and magnetic particle tests on metal parts to
determine if parts meet nondestructive specifications: Reviews test orders to determine type of test
requested, test procedures to follow, and part acceptability criteria. Applies agents, such as
cleaners, penetrants, and developers, and couplant (light oil which acts as medium), to parts, or
heats parts in oven, to prepare parts for testing. Determines test equipment settings according to
type of metal, thickness, distance from test equipment, and related variables, using standard
formulas. Calibrates test equipment, such as magnetic particle, x-ray, and ultrasonic contact
machines, to standard settings, following manual instructions. Sets up equipment to perform tests,
and conducts tests on parts, following procedures established for specified tests performed.
Examines surface-treated materials during penetrant and magnetic particle tests to locate and
identify cracks or other defects, using black light. Moves transducer probe across part when
conducting ultrasonic tests and observes CRT (cathode ray tube) screen to detect and locate
discontinuities in metal structure [ULTRASONIC TESTER (any industry) 739.281-014]. Examines film
when conducting radiographic tests to locate structural or welding flaws. Marks tested parts to
indicate defective areas. Evaluates test results against designated standards, utilizing knowledge
of metals and testing experience. Prepares reports outlining findings and conclusions. May perform
similar tests on nonmetallic parts or structures.
