Fluorescent Penetrant Inspection Process for Non-Destructive Testing
Fluorescent penetrant inspection is used on non-porous materials, such as metals, plastics, ceramics, and glass. This inspection is a critical part of manufacturing safety-critical components. Surface cracks propagate once a critical size is reached. This phenomenon causes catastrophic part failure. It is important that proper processing is performed to reveal indications of surface cracks so that the part can be repaired or replaced. As a safety-critical part goes through its life cycle, it is important to perform routine non-destructive evaluation in the form of fluorescent penetrant inspection to minimize failure of parts in service.
Testing can be done on new products or parts that are in use and need to be analyzed for cracks that may have developed over time.
Automated Fluorescent Penetrant Inspection
An automated Fluorescent Penetrant Inspection (FPI) processing line is a system that is driven by a computer. Automated FPI processing ensures processing that is precisely performed to a preset recipe to ensure that there is no process variability between operators. An automated system can automatically clean, etch, apply penetrant, emulsifier, rinse, dry the part, and apply the developer.
High throughput can be achieved with minimal operator interaction can also be achieved in situ with a processing database that can provide an exact time-stamped history of all processes that were performed on a particular part and be stored for decades! REL specializes in communicating with plant-wide DCS systems that monitor processes throughout the manufacturing process.
