SAE AMS2628

This specification covers procedures for ultrasonic immersion inspection of premium grade wrought titanium and titanium alloy round billet 5.0 inches (127 mm) and over in nominal diameter.

This inspection procedure has been used typically for locating internal defects such as cracks, voids, inclusions, and other structural discontinuities which may or may not be exposed to the surface in billets, but usage is not limited to such applications. Testing normally will be by longitudinal procedure, but shear wave procedure may be added when agreed upon by purchaser and vendor. This specification includes zoned inspection and digital data acquisition.
