How it is done?
1- The technique is based on the ability of a liquid to be drawn into a "clean" surface breaking flaw by capillary action.
2- After an appropriate period of time for penetration has lapsed, called the "dwell time," excess penetrant on the surface is removed and a developer is applied.
3- The developer acts as a blotter and draws the penetrant from the flaw to reveal its presence.
4- Penetrants with a visible dyed added (color contrast) require sufficient white light to insure proper inspection, while penetrants with a fluorescent dye added need to be used in darkened conditions with an ultraviolet or "black light".
Where it is used?
Dye Penetrant inspection or liquid penetrant inspection LPI is used on non porous metal and non metal components to find material discontinuities that are open to the surface and may not be evident to normal visual inspection. This method is used to inspect a variety of product forms including castings, forgings, and weldments. The structural steel, automotive, petrochemical, power generation, and aerospace industries are a few examples that utilize liquid penetrant inspection.
The penetrant strategy is successful in distinguishing surface imperfections in non attractive metals and in an assortment of nonmetallic materials. The strategy is additionally used to examine things produced using ferromagnetic steels and its affectability is by and large more prominent than that of attractive molecule examination. Apparently, the liquid penetrant testing is better than visual investigation yet not as delicate as other propelled types of tests for deducting in-service surface breaks.
LPI offers flexibility in performing inspections because it can be applied in a large variety of applications ranging from automotive spark plugs to critical aircraft components.
