Non-Destructive Testing

Magnetic Particle Testing — Visible (MT)

Critical surface crack detection using visible magnetic particle inspection methods.

The method is applied in situ, on components that remain assembled in the engine room — from crankshaft journals to engine blocks — and yields an immediately visible, documentable result.

✓ Accredited by E.SY.D. — Cert. No. 134 for Testing

Case studies & field applications

Case study — cement mill main journal

Persistent cracks detected after a repair attempt: the journal diameter was reduced by 4 mm through grinding, yet residual crack indications were still visible.

−4 mm
Diameter reduced through grinding

This case demonstrates the importance of follow-up inspections after repair operations.
