The yield strength of CP titanium welds was measured for welds cooled at rates of 10C;s,15C;s, and 28C;s. The results are presented in the following table. (Based on the article “Advances in Oxygen Equivalence Equations for Predicting the Properties of Titanium Welds,” D. Harwig, W. Ittiwattana, and H. Castner, The Welding Journal, 2001:126s-136s.)
