Pratt & Whitney Rocketdyne is equipped with multiple film-less, X-ray imaging vaults and data processes systems. Systems are designed to maximize anomaly evaluation.
Our real-time radioscopy process features X-ray inspections without film. The system is totally digital. All images are created electronically eliminating the expense of film, film processes and disposal of the associated chemicals. The images are viewed on an electronic screen and can be stored on CD-Roms, creating a paperless system.
Radioscopy quality level consists of two components:
- Contrast sensitivity is specified in terms of equivalent penetrameter sensitivity and is measured using image quality indicators (IQI).
- Spatial resolution is specified in terms line pairs per millimeter is measured using a line-pair/mm gauge.
- Our latest X-ray system is a "next generation" system that can handle heavy components while still capable of detailed work on small components - higher sensitivity.
- This process has been demonstrated to be as much as five to eight times faster than standard film radiography.
- The system is computer controlled with teach/learn capability, so it can be trained to perform an inspection process.
Digital Radiographic Inspection and/or Real-Time Radiographic Inspection is used on all major programs for inspection of internal discrepancies in welds and components. Parts up to 2.5" steel equivalent thick can be inspected. There are three enclosed x-ray cells.
X-ray sources ranging from 160 kv microfocus to 320 kv fractional focus can be employed. X-ray cell sizes vary up to 20'L X 24'W X 20'H . One Cell is located within a fine clean facility.
