TC4钛合金真空电子束焊接实验在KL113电子束焊机上进行。实验在加速电压为60kV的情况下改变电子束流、焊接速度、聚焦方式以及扫描方式从而获得一系列的焊接试样,通过对焊接试样的外观成形以及金相分析对比获得最佳参数。采用该工艺流程焊接工件,检测结果显示焊缝各项性能指标满足设计要求。 TC4 titanium alloy vacuum electron beam welding experiments in KL113 electron beam welding machine. Experiments were carried out to obtain a series of welding samples by changing the electron beam current, welding speed, focusing method and scanning mode at an accelerating voltage of 60 kV. The optimal parameters were obtained by appearance appearance and metallographic analysis of the welding samples. Using the process of welding the workpiece, the test results show that the performance of the weld to meet the design requirements.
