  High field pulsed magnets at the NHMFL use high strength conductor wires up
to 90% of their ultimate tensile strength. Therefore it is very important to
ensure that the wires are free of flaws. It is known that in the conductors
cold drawing process, internal chevron crack could occur due to unsuitable
drawing die schedule or inadequate lubrication. These internal cracks occurs
infrequently along the wire, so tensile tests of short samples cut from the
ends of a long length conductor often miss the problem. In addition, small
inclusions on the wire surface can compromise wires fatigue properties. In this
paper, we present results of our non-destructive testing (NDT) inspection of
Glidcop AL60 wires using eddy current testing (ECT), ultrasonic testing (UT)
and x-ray radiography (2D and 3D). Chevron cracks were found in some AL60
conductors by all three NDT techniques. Surface inclusions were found by ECT.
We have developed a long length ECT wire inspection capability.
