What is Dry Magnetic Particle (MPI) Testing?

Dry Magnetic Particle Testing, also known as Dry MPI Testing or Dry MT Testing, is a widely used NDT technique for the detection of surface and near-surface defects in ferromagnetic materials. It involves the application of fine magnetic particles, in a dry form, to the test surface. By applying a magnetic field, any discontinuities or flaws present in the material will create a magnetic flux leakage, making them visible under proper lighting conditions.

Benefits of Dry Magnetic Particle (MPI) Testing:

  • Sensitivity: Dry MPI Testing is highly sensitive in detecting surface and near-surface flaws, including cracks, weld discontinuities, and fatigue cracks, ensuring thorough inspection and reliable results.
  • Time Efficiency: The dry method eliminates the need for wet suspension media, reducing testing time and enabling quicker inspections without compromising accuracy.
  • Cost-Effectiveness: Dry MPI Testing eliminates the costs associated with wet media preparation and disposal, making it a cost-effective solution for defect detection and quality assurance.
  • Portability: Our skilled technicians can perform Dry MPI Testing in various environments, including field inspections, allowing for flexible testing options without compromising the quality of results.

Dry Magnetic Particle (MPI) Testing Process:

  • Preparation: The test surface is cleaned thoroughly to remove any contaminants or coatings that may interfere with the inspection process.
  • Application: Dry magnetic particles are uniformly applied to the surface, either manually or through a dedicated applicator, ensuring full coverage of the area of interest.
  • Magnetization: A magnetic field is then applied to the test piece, magnetizing the material and creating a magnetic flux leakage at any discontinuities.
  • Inspection: A trained technician examines the surface under proper lighting conditions, such as black light or UV light, to identify and evaluate indications or defects.
  • Evaluation and Reporting: The results are analyzed, recorded, and documented in a comprehensive inspection report, providing clients with valuable information for decision-making and quality control purposes.
