Dear Mr Tamer Al Rayes
if you want to detect crack formation during crimping of the end fittings AE can be a valuable online monitoring tool. Please contact me for further information.

Dear Mr. Tamer Al Rayes,

You can detect cracks using the following techniques:
Thermography
Dry-couplat ultrasonics
Coin tape test - for qualitative assessment.

I am more familiar with dry-couplant technique.

With best regards,
