Phased Array UT Level II 40 Hour Refresher  

Detailed Description


This Phased-Array UT Level II Refresher is based on ASNT and ISO Standards topical outlines. The refresher is divided in 3 sections: Self-evaluation test, theory and interactive exercises. The refresher covers manual PAUT as well as automated and semi-automated PAUT.
