Magnetic Particle Testing Equipment
Magnetic particle testing, also called magnetic particle inspection (MPI), is used to find surface and near-surface cracks in iron and steel parts and welds, without damaging them. Asia NDE supplies Baugh & Weedon MPI benches, magnetic yokes, UV torches and lamps, meters and consumables across Malaysia and Southeast Asia. We serve aerospace, oil and gas, railway, automotive and fabrication customers, with calibration and repair support from our Subang Jaya office.
What it’s used for
- Inspecting welds for cracks, on site or in the workshop, with a portable magnetic yoke.
- Checking forgings, castings and machined steel parts on an MPI bench.
- Production and overhaul inspection of aerospace, railway and automotive parts.
- Measuring field strength, UV-A light and residual magnetism to meet inspection standards.
MPI benches and magnetic yokes
An MPI bench holds the part and passes a magnetising current through it, or around it in a coil. A magnetic yoke is a hand-held electromagnet for welds and site work. Baugh & Weedon builds standard, extended, portable and custom benches, and the MY-3 magnetic yoke.
UV lamps and torches
Fluorescent MPI and penetrant inspection need UV-A light at about 365nm, from a UV torch (often called a UV torchlight) or a lamp. We supply the LumaTorch 2 hand-held UV torch, the Iris, Spirit and Opus portable lamps, hands-free Jaguar lamps, the Vista+ smart lamp with camera, and the Apollo 365 overhead panel for inspection booths.

Frequently asked questions
Is magnetic particle testing the same as magnetic particle inspection (MPI)?
Yes. Magnetic particle testing (MT) and magnetic particle inspection (MPI) are two names for the same method. The part is magnetised and fine iron particles are applied. The particles gather where a crack disturbs the magnetic field, which makes the crack visible. It works only on magnetic materials such as most steels.
What UV torch do I need for fluorescent MPI and penetrant inspection?
Use a UV-A torch or lamp with a peak wavelength of about 365nm and enough intensity at your working distance to meet your inspection standard, such as ASTM E1417 or ASTM E1444. A light hand-held UV torch such as the LumaTorch 2 suits most site work. Aerospace work may need a lamp approved to a customer specification.
Do you calibrate MPI benches and meters?
Yes. Asia NDE runs a manufacturer-approved calibration centre, with repair support in Malaysia, for the magnetic particle equipment and meters we supply.
