Abstract：

Choosing Φ57mm×Φ57mm×1.5mm TA2 thin wall T fitting as the researching object,the hydroforming technology producing titanium T fitting with seamless thin wall tube was studied.The results indicate that titanium T fitting can be produced through seamless tube hydroforming for three times or more operations using special equipment.For calculating the hydroforming pressure of titanium alloy,the coefficient 1.15 in the equation for normal metals should be amended to be 1.35-1.6.
