In search of defects

Pontlab, through non-destructive testing, It is able to examine mergers, welding, special molded and machined. The examination can be done on the most varied materials such as: steels, aluminum and magnesium alloys, brass and bronze, titanium, plastic and composite materials.

The analysis allows to detect indications of possible defects that may affect the use of particular.



Through the new tomographic machine Baker Hughes GE V TOME X M 300 , that manages to combine the advantages of Industrial Tomography with the measurement precision metrology, now you can analyze your components with a non-destructive technique.

For more information and to evaluate the potential of our equipment, you can visit the web page dedicated to tomography or view the video on our channel.

Example of a crack


With this technique it is possible to audit the non-ferromagnetic materials, highlighting with precision each surface discontinuity, although very small, of the test piece, such as cracks, porosity, folds. In this test we use a visible red liquid, which it is made to penetrate into the surface discontinuities of the piece. After removal of excess liquid and the application of a detector (usually a liquid adsorbent based on amorphous silica) It is highlighted every single discontinuity thanks to the contrasting liquid / detector.





In the method with fluorescent liquid, a fluorescent penetrant is used (with different sensitivity depending on the particular type of material being examined and), visible after the application of the detector as a result of illumination with black light (lampada in Wood). We have an inspection system with tanks 700x700x500 mm size, with the possibility to carry out checks with post-emulsifiable fluorescent penetrants according to the main rules of mechanical and aerospace (IN 571, ASTM E 1417, AMS 2644, THOUSAND, ASME, FROM, UNI, BS, AFNOR).



The magnetic particle examination (MT) exploit the ferromagnetism of some metals to highlight the anomalies of the magnetic field flux lines near a surface defect. The flow lines, representing the local magnetic field strength, near a discontinuity like a microcrack, a cavity or inclusion, They will thicken or disperse deviating locally and creating an abnormality of the magnetic field at the edges of the defect.

Just spray surfaces or wet them with suitable suspensions of ferromagnetic powders, colored or fluorescent, so that the particles are concentrated aligning along the flux lines of the magnetic field emerging. The different color of the powders or the light emitted by fluorescence in the visible spectrum when illuminated with ultraviolet light (Wood light), highlight each their concentration and consequently defects outcropping or subcortical. The magnetoscopy allows to highlight surface defects and subcortical, not detectable with liquid penetrant, provided that the disturbance of the magnetic field in their surroundings can come up to the surface to be examined.
