Equipment and Accessories for Magnetic Particle Testing: Complete Guide
Equipment and accessories for magnetic particles are key tools in non-destructive testing (NDT), used to detect cracks, inclusions, or other surface or subsurface defects in ferromagnetic materials (such as steel, iron)
🔧 Main Equipment
- Magnetic yokes: Portable equipment with electromagnets that generate a local magnetic field to inspect small or hard-to-reach areas
. - Magnetizing coils: Cables wound around the workpiece to create a circular magnetic field, ideal for bars or pipes
. - Power units: Supply electrical current to yokes or coils, with intensity control (AC/DC)
.
🔧 Essential Accessories
- Magnetic particles: Available as dry powder or wet suspension, in visible or fluorescent colors (require UV light)
. - UV lights: For inspecting fluorescent particles, highlighting defect indications
. - Demagnetizers: Remove residual magnetism from parts after testing
. - Current regulators: Control the intensity of the magnetic field according to the material and defect to be detected
.
| Equipment/Accessory | Function | Application |
|---|---|---|
| Magnetic yoke | Generates local magnetic field | Inspection of welds, shafts |
| Magnetizing coil | Circular magnetic field | Bars, pipes, profiles |
| Fluorescent particles | Indicate defects under UV light | Smooth surfaces, small parts |
| Demagnetizer | Removes residual magnetism | Pieces that require non-magnetized |
Magnetic particle equipment is versatile and complies with standards such as ASTM E1444 or ISO 9934. Contact us for more information and quote on models, certifications, and specific applications.
