摘要

对TC4 钛合金厚板电子束焊接焊缝形状进行了试验研究

分析了电子束焊接过程中不同工艺参数对焊缝形状的影响。结果表明

电子束聚焦电流对焊缝形状的影响较大

随着聚焦电流的变化

焊缝形状变化各异; 焊接速度对焊缝形状的影响较聚焦电流要小

焊接速度不同

焊缝整体形状有所不同

但差异不大; 电子束流对焊缝形状的影响作用较小

焊缝形状的变化近似于整体缩放。

Abstract

Weld shape of TC4 titanium alloy thick plate by electron beam welded is investigated experimentally. The effects of different welding parameters on weld shape is analyzed. It is found that the focus current has a large influence on weld shape

and change of focus current leads to difference of weld shape. The effect of welding speed on weld shape is less than that of the focus current. The integral shape of weld differs

but there is no much greater change in weld shape with changing welding speed. Beam current has a little influence on weld shape. With various beam current

the change of weld shape approximates integral reduction and enlargement.
