Both Magnetic Particle Inspection and Ultrasonic Testing are non-destructive testing methods used to detect flaws in materials. Magnetic Particle Inspection is ideal for surface and near-surface flaws in ferromagnetic materials, while Ultrasonic Testing can detect internal flaws in a wider range of materials. The choice depends on the specific inspection needs and material type.
