Dye Penetrant Inspection

Die Farbeindringprüfung zählt zu den ältesten zerstörungsfreien Prüfverfahren. In diesem Verfahren wird ein flüssiges Penetrant verwendet, um zur Oberfläche hin offene Fehlstellen zu detektieren.  


So werden beispielsweise Risse in Oberflächen von Guss- und Schmiedeteilen und Schweißnähten sichtbar, die selbst bei sorgfältigster Inaugenscheinnahme unerkannt bleiben würden. Die Folge eines unentdeckten Risses kann ein Bauteilversagen nach sich ziehen.

The Procedure

  • The test liquid penetrates any surface defects of a material by capillary action.
  • After the penetrant has been removed from the surface, the applied developer layer generates countercapillarity. This draws the test liquid that has penetrated the defect back to the surface, making the defect visible and measurable.

Your Advantages

  • Dye penetrant inspection can be applied to almost any plant or component of any size, shape, type and material.
  • Whether for aviation or the automotive industry - with the help of our penetrant inspection system, we can perform series part inspection at the Büren site cost-effectively and in compliance with standards.
  • The process can also be used on a mobile basis.
