Examination with penetrant liquids reveals open discontinuities on the surface, even on areas that are difficult to see during visual inspection. The method is fast, sensitive and efficient, suitable for a wide range of materials and complex geometries.

Main applications:

  • Detection of open discontinuities, including those that are visually invisible

  • Inspection of welded joints made of non-ferrous materials (ceramics, aluminum, etc.)

Types of examinations:

  • Penetrating liquids contrast

  • Penetrating liquids fluorescent (with UV light)

Advantages:

  • Very sensitive to small discontinuities

  • Few usage limitations

  • Fast execution and low costs

  • Complex geometries can also be tested

Used equipments:

  • Cleaning agent and water to remove excess penetrant

  • Red or fluorescent penetrant

  • Developer

  • UV lamp and lux meter

At AMG Welding Training SRL, we apply each examination with professionalism and attention to details, ensuring safe and accurate results for every project.
