QCL NY provides Penetrant Testing (PT), also known as Dye Penetrant Testing (DPT), to detect surface-breaking defects in non-porous materials. PT is a proven Non-Destructive Testing (NDT) method widely used in construction and industrial projects to verify surface integrity of welds, metal components, and fabricated parts.
Our PT inspections help contractors, engineers, and project managers maintain quality assurance and compliance while minimizing downtime and costly rework.
Penetrant Testing is a surface inspection method that uses a liquid dye penetrant to reveal cracks or discontinuities open to the surface. The penetrant seeps into defects, and after removing excess penetrant, a developer is applied to draw the dye back out—making defects visible.
PT is effective for detecting:
Surface cracks
Porosity openings
Seams and laps
Leaks on non-porous materials
