Electromagnetic Testing Chapter 3- Electromagnetic Testing

Windowsbased software and laptop computers are used to process the data
and determine the location and extent of the flaws. All data can be recorded
for later display and analysis.
For undersea operations, an unskilled operator can scan structural members
while a more experienced topside operator views results, analyzes data, and
relays information back to the undersea operator.
The method also lends itself to the inspection of heavy machinery and
equipment, bridges, heavy rail equipment, and process pipes and vessels. In
each case, the extent of the structural problem determines the corrective
action that must be taken to extend useful service life. Applications for this
method have been increasing exponentially since the 1990s.
