Liquid Penetrant Inspection Equipment
Liquid penetrant inspection, also called dye penetrant testing, is used to find surface-breaking cracks and porosity in metal and other non-porous parts, without damaging them. Asia NDE supplies Baugh & Weedon penetrant lines, PFINDER penetrant chemicals and UV lamps across Malaysia and Southeast Asia. We serve aerospace, automotive and fabrication customers, with calibration and repair support from our Subang Jaya office.
What it’s used for
- Finding fine surface cracks in castings, forgings, welds and machined parts.
- Checking aerospace and automotive parts on a production line.
- Inspecting non-magnetic metals such as aluminium, titanium and stainless steel, where magnetic particle testing cannot be used.
- Fluorescent inspection under UV-A light for the finest cracks.
Penetrant lines and chemicals
A penetrant line is a set of stainless steel stations, one for each step: apply the penetrant, remove the excess with a remover or emulsifier, wash, dry, apply the developer and inspect. Baugh & Weedon builds lines from manual dip tanks to fully automated systems. We also supply PFINDER fluorescent and visible penetrants, removers and developers, and UV lamps and torches for the viewing booth.

Frequently asked questions
Is dye penetrant testing the same as liquid penetrant inspection?
Yes, both names describe the same method. A coloured or fluorescent liquid is applied to the surface and soaks into any surface-breaking crack. A developer then draws it back out so the crack shows up. The method is also called penetrant testing (PT) or dye penetrant inspection (DPI).
What is the difference between visible and fluorescent penetrant?
Visible (colour contrast) penetrant is usually red and is inspected in normal white light, which suits site work. Fluorescent penetrant glows under UV-A light in a darkened area and shows finer cracks. It is the usual choice for aerospace and production inspection.
