Magnetic-particle examination

Magnetic particle inspection belongs to the non-destructive tests for detecting surface
discontinuities and relatively large slightly subsurface discontinuities. The device can
detect cracks invisible to VT visual method.
Equipment and parameters:
• distance between the poles of the yoke from 25 to 185 mm
• Berthold gauge
• non-destructive magnetic particle inspection (magnetic test – MT)
• assessment of welding non-conformities using visual method according to PN-EN ISO 17638,
PN-EN ISO 17635 standards
• detecting surface discontinuities
