Magnetaufnahmen

Magnetaufnahmen, also known as magnetic particle inspection or magnetic particle testing (MPT), is a non-destructive testing method used to detect surface and subsurface discontinuities in ferromagnetic materials. The process involves magnetizing the material and applying a magnetic particle suspension to the surface. The particles are attracted to the magnetic field leakage caused by discontinuities, forming visible indications that can be evaluated by trained personnel.

The technique is widely used in various industries, including aerospace, automotive, and manufacturing, to ensure the integrity and safety of components and structures. Magnetaufnahmen is particularly effective for detecting cracks, laps, seams, and other defects that may compromise the structural integrity of the material.

The process can be performed using various methods, including wet horizontal, wet vertical, and dry methods. Wet horizontal and wet vertical methods involve applying a liquid suspension of magnetic particles to the surface, while dry methods use dry magnetic particles applied directly to the surface. The choice of method depends on factors such as the material, the type of discontinuity, and the specific requirements of the application.

Magnetaufnahmen is a valuable tool for quality control and maintenance, providing a cost-effective and efficient means of detecting defects that may not be visible to the naked eye. However, it is important to note that the effectiveness of the technique depends on the skill and experience of the operator, as well as the proper preparation and interpretation of the results. Regular training and certification are essential for ensuring the reliability and accuracy of magnetaufnahmen inspections.
