Computed Radiography

Computed radiography replaces film with reusable phosphor imaging plates and a digital scanner, delivering radiographic weld and component inspection with the resolution of film, the speed of digital, and none of the chemical processing. TechCorr deploys CR for field and shop work where turnaround matters: turnaround welds, fabrication support, castings, and pressure-boundary components.

Where computed radiography fits

• New construction and fabrication - weld quality verification to ASME and AWS acceptance criteria without a darkroom.
• Turnarounds and shutdowns - high-volume weld examination with results reviewed on site the same shift.
• Corrosion under insulation and small bore - profile radiography where access limits other methods.
• Castings and complex geometry - internal soundness checks on valves, cast fittings, and machined components.

Why digital radiography beats film

• Minutes, not hours - plates are scanned and images are available immediately for review while the crew is still in the area.
• Digital archive - images are stored and searchable for the life of the asset instead of occupying a film library.
• Adjustable contrast - density, brightness, and contrast are tuned per image, which cuts retakes on marginal film exposures.
• Lower radiation exposure - phosphor plates need less exposure time than film, which shortens exclusion zones.
