本发明为钛铜异种金属电子束焊接方法，具体为种TC4钛合金与T2紫铜的电子束焊接方法，该方法具体步骤如下：首先，进行焊前的准备工作；完成第道偏铜焊接；再使用小束流快速背部对中焊，进行根部成型强化；最后在前两道焊接的基础上，用电子束偏钛合金侧进行焊接。本发明的焊接方法可以有效控制初生的不利取向金属间化合物的分布及含量，提高焊接接头的强度及可靠性。 The invention relates to a method for electron beam welding of titanium copper dissimilar metal, in particular to a method for electron beam welding of TC4 titanium alloy and T2 red copper. The method comprises the steps of first performing preparatory work before welding; finishing primary deflecting copper welding; using small beam to perform back centering welding quickly, and performing root forming intensification; finally on the basis of the primary welding and the secondary welding, using electron beam to perform welding close to one side of the titanium alloy. According to the welding method, the distribution and content of primary harmful orientation intermetallic compounds can be effectively controlled, and the strength and reliability of a welded joint are improved.
