Liquid Penetrant Testing (PT) is a widely used non-destructive testing (NDT) method for detecting surface-breaking defects in non-porous materials. This technique involves applying a liquid dye to the surface, allowing it to seep into any cracks or flaws, and then removing the excess and applying a developer to reveal the defect.
Applications:
Detection of surface cracks, pinholes, porosity, and laps
Inspection of welds, castings, forgings, and machined parts
Suitable for metals, ceramics, plastics, and glass (non-porous materials)
Ideal for final quality control or in-service inspections
Key Advantages:
High sensitivity to fine, open-to-surface defects
Simple, cost-effective, and portable method
No need for electricity or complex equipment
Provides visual, photographic documentation of defects
