Dye Penetrant Testing
Liquid penetrant testing to identify surface-breaking flaws in welds and structures.
Dye penetrant testing is a method for detecting surface-breaking defects in non-porous materials, including metals, plastics and ceramics. A visible or fluorescent dye is applied to the surface, seeping into cracks or flaws, before being drawn out by a developer to reveal imperfections. PT is widely used for weld inspections, fatigue cracking, and component quality checks.
Benefits:
Reveals surface cracks invisible to the naked eye
Works across a wide range of materials
Simple, quick, and cost-effective testing method
