Why FPI Testing Is Essential

Rotor blades in gas and steam turbines are subjected to extreme mechanical and thermal stresses. Even minor defects such as micro-cracks, porosity or bonding flaws can result in component failure and costly unplanned downtime. Fluorescent Penetrant Inspection (FPI) is the industry-standard method for non-destructive testing of safety-critical turbine components, compliant with ASTM E1417 and DIN EN ISO 3452-1.

Conventional manual FPI processes are labor-intensive, time-consuming, and often lack consistent reproducibility.

The kawe FPI testing system integrates all process steps — pre-cleaning, penetration, intermediate cleaning, development, and UV inspection — into a fully automated solution, engineered, built, and validated in-house.
