Multi-sensor inspection system for component testing - towards more reliable ndt applications

Objective



Chemical and Energy producers using Non Destructive
Testing have a strong economical need for improving the
accuracy of the detection and characterisation of defects
in steel components without impacting onto the price of
production.

For achieving both an improvement of defect knowledge and
a global reduction of the NDT cost, the MISTRAL project
proposes to design, to develop and to evaluate multi
sensor approaches on several components shared by most of
the companies in these fields: heat exchanger, pressure
vessel, pipes.

The MISTRAL multi sensor approach for NDT consists of
dedicated multi technique NDT probes, a set of new
processing tools merging the information acquired and an
efficient use of fracture mechanics code in conjunction
with standard acceptance criteria. At any stage of the
NDT process, MISTRAL targets to bring some added value
coming from the complementary aspect of two different
types of NDT data.

MISTRAL demonstrates the efficiency of such a combined
approach for radiography and ultrasound on the one side
and for ultrasound and Eddy current on the other side.
The fusion of different sources of information allows
substantial improvements in detection and
characterisation of defects whereas the use of a combined
probe avoids double sequential acquisition, saving time
as a consequence. MISTRAL aims at

building new probes (more exactly a multi technique
platform configured according to the component tested),
experimenting new acquisition procedures,
implementing new processing tools included in a
portable software library.

The new approach is tested and demonstrated on full scale
components, the impact in terms of maintenance cost and
optimisation is evaluated in details.
