Magnetic particle testing (MT) for reliable detection of near-surface defects
Magnetic particle testing reveals cracks and other discontinuities on and just beneath the surface of ferromagnetic materials — a standard method in weld and material inspection. By deliberately magnetizing the component and applying testing media, even the finest hairline cracks and material separations can be precisely detected.
Key features and benefits:
- Detection of near-surface cracks and discontinuities: Reliable identification of surface flaws, lack-of-fusion defects and cracks that could compromise component safety.
- Suited to ferromagnetic materials: An ideal non-destructive testing method for unalloyed and low-alloy steels, castings and forgings.
- Widely used in weld inspection: An essential part of quality control in steel, vessel and plant construction for fast, cost-effective inspection of welded joints.
