Fluorescent Penetrant Inspection (FPI process) is one of the commonly used Non-destructive testing (NDT) methods.
Fluorescent Penetrant Inspection (FPI process) is a quick and reliable method to inspect your critical metal parts for cracks or flaws before or after the heat treating process. Since FPI is a form of Non-Destructive Testing (NDT), it allows a qualified inspector to make an evaluation without causing damage to your part. This low-cost inspection can not only locate surface-breaking defects in metals, but it can also detect casting and forging defects, weld integrity, cold working defects and fatigue cracks on in-service components.
Fluorescent dye is applied to the surface of an impermeable material to clearly identify surface defects.The basic steps include:
1. Cleaning or preparing the surface to be inspected;
2. Applying the penetrant;
3. Removing the excess penetrant;
4. And then documenting the remaining “highlighted” surface defects.
