Magnetic Crack Detection for Metal Parts - Magkraftndt

Magnetic crack detection is a method for finding surface and near-surface defects in ferromagnetic materials, such as steel and iron. The procedure consists of magnetizing the metal part, and should any interruption of the magnetic field, i.e., due to a crack or defect, occur, a leakage field will be formed. Finely milled magnetic particles are then applied to the surface, where they tend to accumulate in the area of the crack and make the defect visible. The majority of this method is used in industries such as automotive, aerospace, and manufacturing to ensure component safety and performance. This is a very fast, accurate, and economical process that in no way harms the part under evaluation. Magnetic crack detection helps avoid equipment failure by detecting hidden flaws early on, leading to the manufacture of metal components that are of high quality, reliable, and last long.
