What is Magnetic Particle Inspection?
Magnetic Particle Testing (MT), also known as Magnetic Particle Inspection (MPI), is a non-destructive testing (NDT) method used to detect surface and near-surface discontinuities (such as cracks, seams, laps, or voids) in ferromagnetic materials (e.g., iron, steel, nickel, cobalt).
How it works:
- Preclean
- Magnetise the part
- Apply iron particles (dry or wet, often fluorescent)
- Defects cause magnetic leakage → particles cluster → visible indication
- Inspect under visible or UV light
- Demagnetise & clean
Detects: Cracks, seams, voids
Does NOT detect: Deep internal flaws, non-magnetic materials
Pros: Fast, sensitive, portable, cost-effective
Cons: Only for magnetic materials, needs proper field direction
Used in: Welds, castings, aerospace, automotive, rails.
About
PCN Level 1 & 2
This course equips participants with a solid understanding of MPI theory and its practical application on welds, castings & forgings (multi-sector) preparing and qualifying them as PCN Level I or II in Magnetic Particle Testing.
PCN Level 3
This guidance course targets the PCN Level 3 requirements for Magnetic Particle Testing practitioners. Its primary goal is to familiarise candidates with the examination scope and required knowledge level. It helps identify weaker subject areas and provides advice on any additional training needed.
Qualification
Training Days
- Level 1 & 2 combined: 7 days
- Level 3: 4 days
Experience
- Level 1 & 2 combined: 60 days
- Level 3: 240 days
Note: Experience may be acquired either prior to (for Level 1 and 2 entry only) or following success in the qualification examination. However, the chances of success in a PCN examination may be significantly reduced if candidates have little or no current experience in the application of the NDT method in the sector concerned.
