Vetorix Engineering uses an advanced and reliable
Non Destructive Inspection (NDI) procedure for the localization and identification of the most common defects.
Our specific process has been developed by a team of experts (Level 3 Engineers) thanks to the partnership with some of the most prestigious OEM’s R&D Departments.
In order to increase the PoD factor, the best approach is a combined technique, and for the composite materials, is the PHASEOGRAPHY.
It is demonstrated that the PoD will be enhanced almost by 100%, moreover this combined technique allows to reduce the inspection time and related costs.
The starting point is the selection of the NDI methods. In order to define the most reliable NDI procedure, some parameters has to be defined. For example the amount of parts have to be inspected, the required sensitivity , shape and size of the structures, materials, final acceptance criteria and so on. Anyway a standard NDI process start with the NDI method’s selection, going through the specific technique or equipment. The following step is the first batch of inspection aimed to define the sensitivity of the NDI apparatus, the basic calibration, all the settings, the post-processing and interpretation of the results.
After that, a new NDI procedure will be issued as a resume of all the technical and operative details.
The Basic service pack involves some inspection techniques based on different and reliable NDT Methods in order to ensure the best PoD (Probability of Detection), this means to localise and characterise a wide variety of discontinuities, suggesting the best way to understand and fix the common manufacturing problems.
Every NDI technique has some limits, so it is important to know the performance of each single technique via a PoD analysis.
For example, one of the main classifications of the NDI methods is: surface or volumetric. “Surface” are those methods that can not detect flaws on thicker section but only within the “near-surface layer”. Instead “volumetric” are the ones that can provide a good sensitivity in depth.
The most chosen NDI methods, among others, are: Ultrasonics Pulse Echo, Phased Array, Active/passive thermography, bond testers.
It is our strongest relationship program.
We ensure daily presence of our experts at the client's production site, providing NDI service to one or several departments (e.g. QC Dept., R&D Dept., Incoming material Dept.) with accurate analysis on end products or during production line phases. Our in-house program involves the use of inspection technical procedures (including "final acceptance criteria") preliminarily agreed with our client. This inspection process can be used also in on-site inspections, thus ensuring the same inspection quality anywhere in the world.
Flying Inspectors service
Our flying inspectors are certified technicians (Lev.2 or 3 ISO 9712 - ASNT) that can reach you anywhere, providing NDI services on composite materials’ structures.
NDI process is provided with more then one technique for a better testing reliability. Our NDI devices are fully portable enabling us to reach you just in time and anywhere, no matter where you are based.

This technique derives from medical ultrasound and involves the use of specific probes (multi-crystal) with electronic management of the ultrasound beam: this allows the 3D display of internal material defects.
The innovative visualization software enables sectorial "live" scans for an immediate outcome or dedicated views
(in section and plan view) for a more accurate assessment of the defect (characterization and sizing) , thus increasing the reliability of the inspection .
In addition, the post-processing activity allows to record data for future comparisons during the service life of the component.
Our team has been using this technique for over 10 years for the inspection of composite and metal materials.
This method uses mechanical vibrations generated in the component under inspection by means of various types of probes. There is a wide range of techniques depending on the frequency of the input signal: Tap Test (widely used as a basic technique), resonance method, Bond testing, traditional Pulse-echo ultrasound.
The physical principle is based on the perception by the operator of a noise (sound signal - for the Tap test) or the display of a return signal (using a specific device), that is properly processed (e.g.: in frequency or amplitude), read and understood; this provides information on the location and size of any internal defects of the material.

for Non-Destructive Testing
Active Thermography is an incredibly beneficial method for the inspection of structures with complex geometry.
It leverages its "contactless" feature and allows the extension of the inspection to the whole surface of a component.
It takes advantage of heat conduction: a lamp heats the surface under inspection by radiation and a high-resolution thermal camera captures the transient cooling; any thermal anomalies detected indicate the potential presence of internal defects.
Through a dedicated post-processing and a careful analysis of the signals, it is possible to characterize critical discontinuities as delamination, disbonding and cracks, both external or internal.
This technique is a declination of radiography and, thanks to a 360° scan of the component, it allows 3D reconstructions of the external surfaces and the internal volume of the structure.
It is universally recognized to be the best technique in terms of localization and characterization of defects, but it is limited in relation to the size of the object under inspection. The equipment we use in Vetorix Engineering, on the contrary, is revolutionary from this point of view because it allows the analysis of components of significant size.
