This role sets up exposures, verifies image quality, evaluates indications against applicable acceptance criteria, and maintains complete inspection records. The technician also performs magnetic particle testing (MT), visual testing (VT), and liquid penetrant testing (PT) as assigned and within current certifications.

Requirements

Documented NDT Level 2 certification in Radiographic Testing (RT), with a Digital Radiography (DR) or Digital Detector Array (DDA) endorsement or documented submethod qualification.
Documented certifications in MT, VT and PT appropriate to the inspections assigned.
Certification meeting the applicable requirements of at least one of the following: SNT-TC-1A, ANSI/ASNT CP-189, NAS 410 or EN 4179.
Valid Texas Industrial Radiographer card with 3T status.
Ability to pass the required annual near-vision examination (Jaeger 1 or equivalent, corrected or uncorrected) and color-contrast or grayscale differentiation testing.
At least two years of hands-on experience setting up, adjusting and safely operating directional or panoramic industrial X-ray tubes.
Experience handling, positioning and maintaining DDAs or flat-panel detectors.
Proficiency with NDT image-acquisition and enhancement software, including window/level controls and evaluation of signal-to-noise ratio and spatial resolution.
Ability to interpret relevant flaws and acceptance criteria under applicable ASTM, ASME, AWS or API requirements.
Understanding of source-to-detector distance (SDD), object-to-detector distance (ODD) and geometric unsharpness (Ug) in exposure setup.
Strong documentation, communication and attention-to-detail skills, with the ability to work safely with shop and quality teams.
