Product Code:SAE AMS2631
Title:Ultrasonic Inspection, Titanium and Titanium Alloy Bar and Billet
Issuing Committee:Ams K Non Destructive Methods And Processes Committee
Scope:This specification covers the procedure for ultrasonic inspection of wrought titanium and titanium alloy products 0.50 inch (12.7 mm) and over in cross-sectional thickness.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.
