Magnetic Particle Testing

Available6 products
Magnetic particle testing checks for flaws in welds on magnetic metals. Sometimes called magnetic particle inspection (MPI), this form of nondestructive testing (NDT) uses a strong magnet and fine iron shavings. Fine iron shavings are dusted over the surface and the magnetic field draws the shavings to flaws.

Magnetic Yoke & Particle Kits for Dry Non-Fluorescent Testing

Magnetic Yoke & Particle Kits for Dry Non-Fluorescent Testing
These kits include a magnetic yoke and particles for dry, nonfluorescent magnetic particle inspection (MPI) to locate quality issues in welds. Each leg on the yoke is placed on opposites sides of the weld to magnetize the metal. Dry particles are sprinkled on the surface and are drawn to flaws. Dry particle inspection is less likely to detect slight defects than wet particle inspection. Nonfluorescent particle testing is used in well-lighted areas and does not require an ultraviolet light.

Magnetic Particles for Dry Non-Fluorescent Testing

Magnetic Particles for Dry Non-Fluorescent Testing
These magnetic particles are used for dry, nonfluorescent magnetic particle inspection (MPI) of welds. Dry particle inspection is less likely to detect slight defects than wet particle inspection. Nonfluorescent particle testing is used in well-lighted areas and does not require an ultraviolet light.

Contrast Paint for Wet Non-Fluorescent Testing

Contrast Paint for Wet Non-Fluorescent Testing
This contrast paint allows magnetic particles to be seen more easily in nonfluorescent magnetic particle inspection. Contrast paint is applied to the surface before particles are dusted over the surface. Nonfluorescent particle testing is used in well-lighted areas and does not require an ultraviolet light.

Magnetic Particles for Wet Non-Fluorescent Testing

Magnetic Particles for Wet Non-Fluorescent Testing
These magnetic particles are used for wet, nonfluorescent testing. The particles are added to oil or water and applied to the surface using a spray bottle. Wet particles spread more evenly across the surfaces better than dry particles, making wet inspection more likely to detect defects than dry particle inspection. Nonfluorescent particle testing is used in well-lighted areas and does not require an ultraviolet light.

Magnetic Particles for Fluorescent Testing

Magnetic Particles for Fluorescent Testing
These magnetic particles illuminate under ultraviolet (UV-A) light. Particles are sprinkled on a magnetic surface. When a magnetic current is applied, the particles are drawn to the flaw and a UV-A light illuminates the areas of concern.
