Magnetic Particle Testing (MPT), also known as Magnetic Particle Inspection (MPI), is a widely used non-destructive testing method employed in various industries to detect surface and near-surface flaws in ferromagnetic materials. It works on the principle that magnetic fields are distorted in the presence of defects, making them visible when magnetic particles are applied to the surface.
Applications of Magnetic Particle Testing :
Weld Inspection
Forging and Casting Inspection
Quality Control in Manufacturing: MPT is utilized during the manufacturing process to ensure the quality of machined or fabricated components, detecting defects that may have occurred during production.
Maintenance and Repair
Aerospace and Automotive Industry:
Advantages of Magnetic Particle Testing :
Surface and Near-Surface Detection: MPT is highly effective in detecting surface and near-surface flaws such as cracks, seams, laps, and inclusions. This makes it particularly useful for inspecting welds, forgings, castings, and other ferromagnetic materials.
High Sensitivity: It can detect small defects, including hairline cracks, that may not be visible to the naked eye, ensuring accurate and reliable results.
Rapid Inspection
Portable and Versatile: MPT equipment is often portable and can be used in different inspection scenarios.
