ACFM
offers significant benefits to many industries. Inspections can
be conducted on components in service, reducing operational downtime.
With automatic detection and sizing of defects and audible alarms
dependant on the severity of defect encountered, less reliance is
placed on the operator and the overall reliability of inspection
improved. Additionally data is available for third party review
without need for re inspection
Accuracy and information
on crack depth means resources can be prioritised, safety improved
and unnecessary repairs eliminated.
Inspection methods such
as ultrasonic testing, magnetic particle inspection and penetrant
inspection have weaknesses - particularly when trying to detect
shallow surface breaking defects in real-world situations - where
there is a heavy reliance on operator technique and interpretation.
Also recording of inspection data is not easy and is generally not
carried out.
TSC have developed general
ACFM inspection systems for use in several industries, including
railway, theme and amusement park, nuclear, space, underwater, military
and civil engineering.
Four systems are shown
below, all based on the AMIGO, though all designed and built to
specific customer requirements and applications.

Bombardier
Inspection System
Bombardier Transportation
commissioned a specialised ACFM system from TSC for their
particular requirements for inspection within the rail infrastructure.
The AMIGO instrument was modified and specialised probes designed
and built, resulting in a system that saved the company expensive
down time, increased reliability of inspection and enabled
a varied range of components and geometries to be inspected
with one compact, portable system.
TSC are able to
design and build similar general inspection systems tailored
to a clients specific requirements, applicable to any industry
sector |

Boiler
Waterwall Inspection System
TSC
Inspection Systems have provided a solution to the power generation
industry for the rapid detection of transverse surface breaking
cracks on the internal waterwalls of boilers - commonly occurring
on the tube fins, resulting in the client being able to rapidly
assess the condition of the walls during the limited time
available during a shutdown
The AMIGO was built
as a high frequency, high speed instrument, capable of rapid
deployment and data collection.
TSC are able to
design and build systems and probes contoured to any particular
geometry. |

Storage
Tank Inspection System
The aim of Robot
Inspector is to develop a semi-automated inspection vehicle
for measuring plate thickness and detecting corrosion and
cracking in the plate or welds between plates. One of the
main target application areas is the inspection of storage
tank floors.
The project combines
ultrasonic and ACFM inspection tools, all deployed from the
one robotic crawler. The partners include companies experienced
in software, robotics and positioning systems as well as NDT,
from a range of European countries, working in collaboration. |

Nuclear
Reactor Inspection System
The photograph shows
the probe from a system designed to be robotically deployed
on the underside of a nuclear reactor head, during shutdown.
The reactor head
is carbon steel with a ¼" lining of inconel. The
control rod drive mechanism (CRDM) attaches above, penetrates
through a series of nozzles and attaches to the control rods
within the core. Each nozzle is constructed of inconel-600
and has a thermal interference fit in the head bore hole.
A 'J' groove weld of inconel (alloy 182) provided a barrier
for the coolant.
Previous means of
inspection with manually deployed penetrant testing was considered
undesirable due to the high doses of radiation in the area
around the reactor nozzles.
