Liquid Penetrant Inspection
Liquid penetrant inspection (LPI, or PT for "penetrant testing") is used to inspect parts and weldments for open-to-surface discontinuities. A penetrant solution is applied to a clean, bare surface and allowed to dwell for a certain amount of time. This allows the penetrant to be drawn into tiny cracks and other discontinuities that are of interest to the inspector. The surface is then wiped clean and a developer applied. This draws out the trapped penetrant, which soaks through the developer on the part surface and reveals tiny indications which may not be visible to the naked eye. Penetrant is used instead of magnetic particle inspection when looking for cracks in non-ferrous metals or in plastics and composites.
LPI can be performed using visible or fluorescent dyes, and is available in a wide variety of sensitivity levels.
