Radiographic Testing
Radiographic testing uses X-rays or gamma radiation to produce an image of internal material and weld conditions.
What this term means in maintenance
Radiographic testing uses X-rays or gamma radiation to produce an image of internal material and weld conditions.
Common applications
RT may inspect:
- Welds
- Castings
- Pressure components
- Piping
- Structural joints
Practical example
A pipeline weld is radiographed to identify internal porosity, lack of fusion, or inclusions.
Advantages
Radiography provides a permanent image and can show internal volumetric defects.
Safety
Radiation control requires qualified personnel, exclusion zones, permits, monitoring, and regulatory compliance.
Common mistake
Using radiography without considering defect orientation can miss planar flaws poorly aligned with the beam.
How this term differs
Radiographic Testing is X-ray or gamma imaging of internal conditions. It is related to Ultrasonic Testing, Eddy Current Testing, and Nondestructive Testing, but these terms describe different records, measures, roles, strategies, or decisions and should not be used interchangeably.

Nondestructive Testing
Nondestructive Testing, or NDT, examines materials, components, and structures for defects without damaging their intended usefulness.
Static Equipment
Static equipment is process or facility equipment without a primary rotating mechanism, such as vessels, tanks, piping, structures, and heat exchangers.
Permit to Work
A permit to work is a formal authorization confirming that defined hazards, isolations, precautions, responsibilities, and validity conditions are controlled before high-risk work begins.
