Applied Technical Services provides magnetic particle inspection as a method of nondestructive testing. Also known as MPI, magnetic particle inspections are used for detecting surface and near-surface discontinuities. Our technicians are able to detect flaws in ferromagnetic materials by inducing a magnetic field directly or indirectly into a component. Many of the methods used are dry particle and wet suspension while applying continuous and residual magnetization. Magnetic particle inspection is one of the most cost-effective inspection methods used and, furthermore, offers a short turn-around time.
