Liquid penetrants

Liquid penetrants

The liquid penetrant method “Zyglo” is designed only for the detection of defects that are surface connected by the visibility of a fluorescent dye bleeding from within the defect. Following an adequate waiting time, the excess penetrating liquid is removed from the surface and a development substance applied in order to extract the liquid from the defects and intensify the visual evidence, to increase the sensitivity of the test.

Liquid penetrant applications:

  • Testing of aerospace accessories
  • Testing of accessories in the automotive industry
  • Testing of crane welds and lifting accessories
  • Testing of ceramic, glass and plastic products
  • Testing of defects in welds
  • Testing of defects in castings
