Can MPI be performed on complex geometries?

Magnetic Particle Inspection (MPI) is indeed capable of being performed on complex geometries, and specialized fixtures play a crucial role in adapting the inspection method for such shapes. This is important because the effectiveness of MPI relies on the uniform application of a magnetic field, which can be challenging to achieve on intricate designs.

Using specialized fixtures allows inspectors to create a controlled magnetic field around the complex geometry, ensuring that the magnetic particles can effectively cluster at defects like cracks or surface discontinuities. These fixtures may employ different approaches, such as mechanical supports or magnetic yokes, which help in directing the magnetic field appropriately, thus enhancing the sensitivity of the inspection process.

This versatility of MPI in accommodating various shapes is one of its significant advantages in non-destructive testing, as it enables inspectors to evaluate a wide range of components in numerous applications, from aerospace to automotive industries, where intricate shapes are common.
