WebFluorescent or visible penetrant with color contrast are used with one of the following three penetrant processes, namely, water washable, post-emulsifying, and solvent removable. The combination of fluorescent or visible penetrant with the three processes results in six possible liquid penetrant techniques. Fluorescent penetrant inspection (FPI) is a type of dye penetrant inspection in which a fluorescent dye is applied to the surface of a non-porous material in order to detect defects that may compromise the integrity or quality of the part in question. FPI is noted for its low cost and simple process, and … See more There are many types of dye used in penetrant inspections. FPI operations use a dye much more sensitive to smaller flaws than penetrants used in other DPI procedures. This is because of the nature of the See more There are six main steps in a fluorescent penetrant inspection process: Step 1: Initial cleaning Before the penetrant can be applied to the surface of the material in question one must ensure that the surface is free of any contamination such as See more • The method requires thorough cleaning of the inspected items.

WebWith excessive fluorescent background, penetrant indications may blend in with the background instead of standing out for easier inspection. Lower sensitivity penetrants have less background than a higher sensitivity penetrant but … WebFluorescent penetrants are generally more capable of producing a detectable indication from a small defect. Also, the human eye is more sensitive to a light indication on a dark background and the eye is naturally drawn to a fluorescent indication. cuisinart toaster convection oven hot dogs
