Digital Radiography offers the promise of economic and environmental advantages over traditional film based
inspection. Boeing Commercial Aircraft Group has an on-going effort to evaluate this emerging radiographic
method for production of aerospace hardware. Included in this effort was a program to evaluate the potential
for utilizing amorphous silicon based digital radiography for the inspection of inconel weldments in engine
ducting. For this particular program, probability of detection (POD) studies were conducted to compare the
reliability of digital radiography with the existing production processes that utilize film radiography and
image-intensifier based radioscopy. Cycle time studies were also conducted to determine the potential
economic benefit for switching to the new process. The methodology and findings of this comparison are
presented.
