Container weld inspections are crucial to ensure structural integrity and safety. Among the non-destructive testing methods available, Magnetic Particle Inspection (MPI) stands out. This technique utilizes magnetic powders to reveal defects and discontinuities in ferromagnetic materials without causing any damage.
The process of MPI involves magnetizing the ferromagnetic workpiece, which leads to localized distortions in the magnetic field lines when discontinuities are present. This results in a leakage magnetic field that attracts magnetic powders applied to the surface. When appropriately illuminated, these powders form visible indications, allowing for the identification of location, size, shape, and severity of any defects.
For effective flaw detection, TLS employs black magnetic paste during MPI. This specific approach boasts high sensitivity in detecting even the smallest surface imperfections. The procedure comprises the following steps:
All our Quality Assurance personnel undergo rigorous certification examinations. At TLS, we uphold an unwavering commitment to product quality, delivering only after thorough confirmation that our offerings align with stringent quality inspection standards.

For effective flaw detection, TLS employs black magnetic paste during MPI. This specific approach boasts high sensitivity in detecting even the smallest surface imperfections. The procedure comprises the following steps:
- Application of Magnetic Levitation: A slow and controlled application of magnetic levitation over the workpiece prevents the washing away of magnetic imprints.
- Utilization of Fixed Devices: Implementing fixed devices streamlines the process, ensuring ease of operation and high efficiency.
- Demagnetization: This step reduces residual magnetism in the inspected workpiece, enabling subsequent processing or normal usage.
- Removal and Drying: After the magnetic particle inspection, any residual magnetic levitation on the surface is removed and dried.
