| # | Lesson | Type |
|---|---|---|
| 01 | Presentation & Recording of Test Results How MPI indications and test outcomes are presented and recorded — required fields, format conventions and traceability to the test piece. | Lesson |
| 02 | Acceptance Criteria Reading and applying acceptance criteria from codes and specifications to classify indications as acceptable or rejectable. | Lesson |
| 03 | Reporting, Location & Preservation of Records Marking indication location on the part, formal report content, and how long inspection records must be preserved per code requirements. | + Knowledge check |
| 04 | Demagnetization & Reasons Why parts are demagnetized after MPI — effects of residual magnetism on machining, welding, instruments and in-service performance. | Lesson |
| 05 | Reasons — Demagnetization NOT Required Situations where demagnetization can be safely skipped — material, geometry, end-use and downstream-process considerations. | Lesson |
| 06 | Demagnetization Methods AC, DC reversing, coil pass-through and heat-above-Curie methods of demagnetization, and how to choose between them. | Lesson |
| 07 | Measuring Residual Magnetism Using a residual field indicator / Hall-effect gauss meter to verify residual magnetism is below the specified limit (typically 3 G / 240 A/m). | + Knowledge check |
| 08 | Safety Precautions Electrical, chemical, UV-light and material-handling safety precautions for MPI operators — PPE and exposure limits. | Lesson |
| 09 | Advantages of MT Key advantages of Magnetic Particle Testing over other surface NDT methods — speed, cost, sensitivity and surface-prep tolerance. | Lesson |
| 10 | Limitations of MT Material, geometry, orientation and subsurface-depth limitations of MT — and how to design around them. | + Knowledge check |
| 11 | MT Equipment, Accessories & Consumables — Practical Video Walk-through of standard MT equipment: yokes, prods, stationary benches, accessories, magnetic medium and consumables used on the shop floor. | Lesson |
| 12 | Electromagnetic Yoke Deadweight Check — Practical Video Step-by-step deadweight verification of an electromagnetic yoke — setup, lifting test and pass/fail interpretation. | Lesson |
| 13 | Prod-Type Equipment — Practical Video Operating prod-type MT equipment safely — electrode placement, current settings, arc-strike prevention and indication scanning. | Lesson |
| 14 | Stationary Equipment — Headshot Technique — Practical Video Headshot (direct contact) technique on a stationary bench — clamping, magnetising current, bath application and inspection under UV light. | Lesson |
| 15 | Automated Equipment — Practical Video Automated MT lines — load/unload, multi-axis magnetisation, automatic bath application and operator role in indication verification. | Lesson |
| 16 | Wet Bath Settling Test Settling-test procedure for wet magnetic medium — pear-shaped centrifuge tube, settling time and acceptable particle-concentration range. | Lesson |
| 17 | Final Magnetization Demo & Conclusion Closing practical demonstration tying together magnetisation, indication detection and post-test demagnetisation — module conclusion. | Lesson |
