Lamellar tear vs Laminations and Z through Test
Lamellar tear vs Laminations and Z through Test
(OP)
Dear All
I want to ask some topic which i'm not understand
1.What the differences between Lamellar Tear and Lamination? Because in some reference they are similar and not quite different?
2. Is it Z through test (through thickness test) can detect lamination also, beside its primary functions to detect lamellar tear?
3. If plate was detected have lamellar tear, what actions take to repair that plate, so the plate can reused?
Thank you for response and answer
Regards

Laminations are defects in materials, and you can review on your own.

Z refers to through thickness direction, and volumetric examination.
Typically, lamellar tears are associated with welding and banding in steel plate. If lamellar tears occurred in service, I would not repair the plates because it would re-occur.
