(OP)
Does anyone know why 100% ultrasonic inspection is mandated for e-beam welds?

I suppose the thinking is that, you could also have planar flaws. Thus, UT is sensible because it could pick up flaws that X-ray couldn't.
It seems though that 100% inspection is overkill in certain cases based on part dimensions and weld characteristics.
For reference, the paper with the comparison between x-ray and UT is:
Jack Spanner, "Effectiveness of Substituting Ultrasonic
Testing for Radiographic Testing for Repair/Replacement"
ASME Conf. Proc. 2005, 33 (2005)
