Penetrant Testing (PT)

Penetrant Testing (PT)

0.00

We use PT to locate cracks, porosity, and other defects that break the surface of a material and have enough volume to trap and hold the penetrant material. Liquid penetrant testing is used to inspect large areas very efficiently and will work on most nonporous materials.

Benefits of PT:

  • Large surface areas or large volumes of parts/materials can be inspected rapidly and at low cost
  • Parts with complex geometry are routinely inspected
  • Indications are produced directly on surface of the part providing a visual image of the discontinuity
  • Equipment investment is minimal
