Magnetic Particle Testing (MT) is a widely used non-destructive testing method that plays a vital role in identifying surface and near-surface discontinuities in ferromagnetic materials. By applying magnetic fields and fine magnetic particles, this method makes even the smallest cracks or flaws visible, ensuring product integrity and safety across industries. MT is a practical solution for detecting issues in welds, castings, and critical machine components where structural strength is paramount. Its effectiveness, speed, and accuracy make it a preferred choice for industries such as aerospace, automotive, construction, and energy, where material performance is essential.
