On July it has held the 1st Convention about the Non destructive testing in naval field; it was organized by the Italian Association Not Destructive Tests (AIPnD) in Genoa. 

The Conference, born from the idea of presenting an overview of the issues related to non-destructive controls in the naval sector, has allowed Gilardoni to present the use of technical about laser shearography. 

Laser shearography (LS) is a non-destructive method (NDT) used to detect subsurface defects in various types of structure, especially composite materials by analyzing deformations due to a known stress imposed on the object to be analyzed.

The excitation methods that can be used to induce a small deformation are:

  • thermal excitation
  • depression
  • vibration, acoustics and mechanics.

The method involves one-sided accessibility, no means of contact, and a high inspection rate in the order of mq/min.

The shearography technique in the field of ship inspections is applicable at:

  • Hulls
  • Rudders
  • Components made of composite material

The detectable defects are:

  • Delaminations (Ply-Plys)
  • Necklines (Ply-Core)
  • Cleavage (Kissing Bonds)
  • Impact damage (BVIDs)
  • Corrosions- Water inlet
  • Clique in the heart
  • Crushing in the core

Obviously the SL is also used in many other fields including Aerospace, Aeronautics, Automotive, Wind, etc.

During the Convention has carried out a deepening tied to the formation, qualification and certification of the ndt operators in naval field.

This meeting was undoubtedly an important moment for Gilardoni and allowed him to discuss and share information on different themes in the sector.
