Very specific techniques


In additional with usual means of investigation used by our technicians to estimate the necessary repairs to a component, other types of tests can be used.

These are highly advanced processes, for which we've trained our technicians.
In some cases, they have been qualified by specific certifying authorities.

NON DESTRUCTIVE TESTING (NDT)


NDT is used to inspect sample parts for cracks, without having to affect their physical integrity. If the part is conform, it can be immediately reused to repair the component from which it comes.

At AIR SUPPORT, we use DYE PENETRANT INSPECTION and MAGNETIC INSPECTION:


Let our expert presenting it to you :

  • Dye Penetrant Inspection:

« This process is used to control the face of the component.

We apply above a fluorescent product, which is going to enter in the possible defects. After 20 minutes of impregnation, the piece is rinsed. However, the liquid having returned into the imperfections is going to stay. So, after a drying time, when the component is passed in the "revelation area", a tool which is going to act as a blotting paper, the liquid is going to reveal itself. If there are defects, they are going to stand out, by a bright indication

  • Magnetic Inspection:

"It allows to control the face and sub-face.

This technic is for ferrous & aimantable steels components. Firstly, we apply above a fluorescent product (oil which contains fine particles of ferrite). Then, the component is submitted to a magnetic field, which is going to create " field lines" (the way followed in the component). However, these lines will be diverted if they meet a defect in the piece. This abnormality will lead to the accumulation of ferrite particles which, at the time of the final control, will appear with bright indications

TRIDIMENSIONNAL MESURES (TMM)



It is a tool which makes it possible to check the dimensions of a part.

In the field of metrology, the TMM measures on 3 axes (X, Y, Z – positive and negative) dimensions of the studied component.

This one is fixed on a gauge and the feelers with head in ruby (inalterable matter) of the machine turn around, according to a preset course by programming.

At each the right moment envisaged, it comes to touch the component (from which the catch by palpation got its name), before going to renew the operation on the following point.

Although this analysis can be realized manually, the incredible precision of the TMM allows an incomparable exactitude in its measurements.
In this way, in the event of divergences in the dimensions raised with the model given by the manufacturer, our technicians can suspect the presence of an anomaly.
An in-depth analysis will be carried out, such as for example by NDT tests.
