Fluorescent Penetrant Testing
What Is It
Surface Crack Detection Using UV Fluorescence
Some cracks are too fine to see under normal light - until you switch the lights off.
IRC’s Fluorescent Penetrant Testing (FPT) reveals surface-breaking cracks and discontinuities using UV fluorescence, making fine defects highly visible.
Our FPT service is ideal for:
- Critical welds
- Castings & forgings
- Machined components
- Fine surfaces
- Non-porous materials
Why FPT
Why Choose Fluorescent Penetrant Testing?
FPT provides higher sensitivity where conventional visible dye testing may not be enough.
Higher Sensitivity
Reveals finer, tighter surface-breaking cracks.
Any Non-Porous Material
Suitable for aluminium, stainless steel, titanium, and more.
Immediate Results
Defect indications become visible instantly under UV light.
Critical Components
Ideal where missing a small defect can have serious consequences.
How It Works
Our Fluorescent Penetrant Testing Method
A proven process designed to reveal even fine surface-breaking defects.
Surface Preparation
Clean and prepare the component surface.
Penetrant Application
Apply fluorescent penetrant and allow sufficient dwell time.
Excess Removal
Remove excess penetrant from the surface.
Developer Application
Apply developer to draw trapped penetrant back to the surface.
UV Inspection
Inspect under UV light to identify and evaluate glowing defect indications.
Our Toolkit
Why Fluorescent Penetrant Testing?
Higher Sensitivity
Detects fine cracks that may remain invisible under normal lighting.
UV Fluorescence
Bright defect indications provide clear visual identification.
Non-Destructive
Inspects components without damaging their surface or function.
Fast Inspection
Immediate indications allow quick inspection decisions.
Where We Apply It
Where We Apply It
FPT is suited for critical components where fine surface defects can affect reliability and performance.
