The Model Visual Eddy, eddy current test system
utilizes the eddy current test technique method which very effectively locates
SUSTAINED LOAD CRACKING (SLC) in high pressure aluminum cylinders. These aluminum cylinders are used for
SCUBA diving, fire-fighting, carbonating
beverages and in the medical field. Some
of these cylinders may develop cracks and may be seen during visual
inspection. These cracks can cause
leaking and ultimately lead to catastrophic failure (explosion).
In sustained load cracking, small radial cracks start
at the base of the threaded neck area and propagate toward the shoulder (the
cylinder body) and up in to the neck (threaded area) as the cracks grow
deeper. Eventually, these cracks can
become quite deep and can lead to tank rupture.
Eddy current techniques can detect these cracks in
the initial stages of formation long before there is any real hazard.
The
Visual
Eddy is very easy to operate. It was
designed to be used by people with minimal formal eddy current training. Power on the unit and it will return to the
previous setup and
set the internal controls to the previous
values via the internal microprocessor.
It is necessary to verify calibration of the unit by rotating the aluminum test ring over the sensitive
area on the probe and note if the pulse that is generated on the graphic
display is of the proper size. Next, the
probe is threaded completely into the cylinder neck until the probe no longer
turns easily. The probe is rotated out
of the neck. If the eddy current sensor crosses over a crack, a pulse is displayed
on the screen.
The turntable, while not mandatory, is
an integral part of the
inspection system and serves two purposes.
The starting and stopping motion of the probe as it is manually screwed
out of the cylinder may lead to false indications. The turntable offers constant and consistent
rotational speed. The turntable also
eliminates the operator fatigue of turning the probe into the tank thereby
increasing productivity.
