Latest Electromagnetic
Technology Device Improves
Inspection Accuracy
and Repeatability
Eddy currents are electrical currents induced
within conductors by changing
magnetic fields. They are commonly used
in nondestructive evaluation (NDE) and
corrosion monitoring of structures with
painted surfaces. The work of eddy current
technicians, who specialize in the electromagnetic
modality, requires a high degree
of accuracy even when working under
challenging testing conditions.
Traditionally, technicians relied on service
bulletins or paper-based instructions
that outline each step of the test to ensure
accuracy and their own safety. This,
however, can add to the complexity, cost,
and timeliness of the testing. It also provides
opportunity for error, often requiring
a second technician to read the instructions
and record the result, which itself is
an error trap.
General Electric's (GE's) Measurement
and Control business recently introduced a
first-of-its-kind, handheld electromagnetic
inspection technology that integrates testing
intelligence and industry experience
into an easily adaptable platform. The GE
Mentor EM allows technicians to access information
and guidance needed to perform
efficient and accurate weld, rotary, and surface
inspections (Figure 1). By decreasing
the need for paper-based service bulletins
and cumbersome manuals, the device replaces
legacy processes and takes full advantage
of the latest technology.
