Seattle Dye Penetrant Testing

Dye Penetrant Testing (DPT) process:

  • After the plates have been properly cleaned and dried.
  • The plates are brought into the spray booth area where the dye gets sprayed on one side only.
  • After the dye is applied the plates are stacked to allow the dye to work into the material.
  • Plates are then moved to the dark room area where black fluorescent lights are used to identify the pin holes or cracks.
  • All pin holes and cracks are marked with a black felt permanent marker.
  • Dye is washed off.
  • Plates are dried.
