| Certifications | ASNT Level I/II/III, AWS certifications | ASNT Level I/II/III, ARRT certification |
| Work Environment | Industrial sites, manufacturing plants, construction | Industrial facilities, power plants, manufacturing |
| Industry Usage | Non-destructive testing (NDT) for welds and materials | Non-destructive testing (NDT) using radiography |
Both roles involve non-destructive testing in industrial settings and require similar certifications. The main difference is the testing method: ultrasonic testing uses sound waves, while radiographic testing uses X-rays. Candidates should choose based on their preferred testing technique and certification path.
