Inspecting carbon steel welds
with magnetic particles poses several problems, such as:
The paint needs to be removed
and extensive surface preparation is required.
There are environmental concerns
because of the harsh chemicals that are used.
The process is highly susceptible to field conditions.
There’s no permanent record of data.
And it’s not well-suited for rope access inspections.
The NORTEC 600 Weld Inspection Solution
is an ideal replacement
for magnetic particle inspection,
it features several benefits such as:
Inspection through paint or coatings
measuring up to 2mm thick.
It’s more environmentally friendly
since no chemicals are involved.
Evaluation of defect depth and length.
Data reporting and archiving.
And, it is rope-access ready.
Inspection Through Paint
Eddy current technology
uses a magnetic field to couple the sensor to the part,
so a certain distance between
the probe and the part is permissible.
That means that the NORTEC 600 Weld Inspection Solution
can detect defects through up to 2mm of paint
or nonconductive coatings.
The ability to inspect through the paint
or coatings makes removing these layers unnecessary.
Eddy current technology
also requires minimal surface preparation.
As no chemicals are involved in the process,
the NORTEC 600 Weld Inspection Solution
contributes to a cleaner environment.
Defect Depth and Length Evaluation
The NORTEC 600 Weld Inspection Solution
features unique tools that facilitate
the evaluation of an indication’s depth and length.
The depth of a surface-breaking indication
can be evaluated based on the peak-to-peak amplitude
in the impedance plane.
Deeper indications produce larger amplitudes.
The new real-time readings
provide instantaneous amplitude and phase values
that can be used for comparison
with the calibration defects.
This peak-to-peak measurement
is a very reliable and consistent way
to determine an indication’s depth
because variations in the operating point
have no effect on it.
The NORTEC 600 Weld Inspection Solution
also enables defect length evaluation.
The length can be estimated based on
the -6 dB threshold on each side of the flaw.
The combination of the NORTEC 600
real-time readings
and instant reference signal
make estimating an indication’s length extremely easy.
Complete Archiving Solution
Unlike MPI, recording inspection results is efficient
with the NORTEC 600 Weld Inspection Solution.
Files can be saved at any time
during an inspection.
Those files can be previewed on the instrument
or downloaded to a computer
where a full report can be easily produced
in the NORTEC PC software.
Rope-Access Ready
The NORTEC 600 is ideal for rope-access inspection.
It features a highly portable and rugged casing,
4-point anchors,
and its interface is also extremely intuitive.
Olympus offers a wide selection of rugged weld probes
and probe kits to suit your inspection needs.
The NORTEC 600 Weld Inspection Solution
is a major improvement over the MPI method.
