~ 2007 FFC Technical Paper Excellence Award Winner ~ Welds have been inspected by radiography for years, but this technology has major drawbacks: low detection rates for critical planar defects (i.e., cracks and lack of fusion), subjective interpretation, no vertical sizing capability, significant safety hazards, licensing issues, chemical wastes, plant closures and is generally slow. For decades, the main alternative was manual ultrasonics, which is also slow, subjective and normally has little hard-copy record. Author: M. Moles (Olympus NDT)
