Liquid Penetrant Inspection (DPI/PT)

Level 2

Course Overview

Liquid Penetrant Inspection is highly effective in examining the integrity of materials such as metals, plastics, ceramics, and glass. It tests for surface defects like cracks, porosity, laps, or other discontinuities can potentially compromise their integrity.

This course aims to provide training for personnel tasked with identifying surface-breaking indications on non-porous materials. Liquid Penetrant Inspection is known for its simplicity and cost-effectiveness as a non-destructive testing (NDT) method, allowing for efficient inspection of large areas and a wide variety of materials. This technique finds widespread application across industries such as aerospace, manufacturing, automotive, and power generation. It enables the examination of welds, castings, forgings, and other components for surface defects.

Liquid Penetrant Inspection is available in two techniques: fluorescent and colour contrast methods.
