Conclusion
Non-destructive inspection of metals

Metals are widely used in the manufacture of industrial infrastructure and transportation equipment. Safety and operational constraints are often critical, requiring the integrity of many components to be verified.

In this context, an essential aspect to consider during their manufacture, as well as during monitoring and maintenance operations, is the use of non-destructive testing techniques to detect defects that could compromise the performance of the part in service.

The acoustic and electromagnetic properties of metals allow for the use of a wide range of non-destructive techniques:

• Ultrasound has a wide variety of applications and can be used to detect defects throughout the entire volume of metal to be inspected, with reading made easier by the increasing use of imaging techniques. Its use may be limited by the need to use a coupling agent, which...
