Penetrant Inspection Advantages

  • Liquid Penetrant Testing can detect linear discontinuities
  • When performed properly with proper process controls and qualified technicians, it will provide reliable indications.
  • It can locate surface discontinuities on the final finished surface of test objects
  • It can be useful to detect fatigue damage or production problems

Penetrant Inspection


Visible Dye and Flourescent Penetrant Inspections are utilized. Welds, castings, inservice fatigue crack detection and machined parts (with pre-penetrant etch) are processed.


When a flourescent penetrant liquid is placed on a clean, dry surface it will wet the surface properly and migrate down by capillary action. This causes the penetrant to enter discontinuities that are open to the surface. After excess surface penetrant surface is removed, only the penetrant inside the discontinuities remains forming a penetrant indication. The use of contrasting developer aids makes the indications easier to see.
