Purpose

This specification covers the procedure for ultrasonic inspection of wrought titanium and titanium alloy products 0.25 inch (6.4 mm) and over in cross-section (thickness) or diameter.

When specifically requested by purchaser, this specification may be used for metals other than titanium.

Application

This procedure has been used typically for locating internal defects, such as cracks, voids, spongy areas, and other structural discontinuities, which may or may not be exposed to the surface, but usage is not limited to such applications.

Testing normally will be by longitudinal wave procedure, but shear wave procedure may be used when agreed upon by purchaser and vendor.

The requirements of this specification may be met by performance of ultrasonic inspection to AMS2628 as follows:

Perform UT to AMS2628 for material up to and including 10 inch (254 mm) diameter to meet the Class AA requirements specified herein.

Perform UT to AMS2628 for material over 10 inch (254 mm) diameter to meet the Class A1 requirements specified herein.
