Conclusion#
X-ray imaging is mainly limited by the thickness of the part to be checked. The detectability of plane defects is less good than in ultrasound, but automation of control is very easy.
Pros
no coupling
2D(+t), 3D(+t) imaging
metrology
volumic defects: good sensitivity
automatization
Cons
radioprotection & cost
crack, delamination, planar defect: poor sensitivity
large thickness: poor transmission (\(>\) a few cm of metal)
