| 摘 要： | 为了探索电子束深熔穿透焊接原理,针对20mm厚TC4钛合金中厚板材开展了电子束焊接工艺实验,分析了电子束焊接过程焦点动态变化特性,研究了焊接速度、工作距离对电子束焊接焦点动态变化特性的影响.结果表明,随着焊接速度增加,临界穿透束流增大,焦点动态变化特征曲线上移;随着工作距离的增加,动态焦点逐渐向下移动;保持其他参数恒定,随着聚焦电流增加,电子束焦点动态变化,焊缝形貌由钉形向钟罩形过渡. |

| Abstract: | The processing of electron beam welding(EBW) was studied for TC4 titanium alloy with 20mm thickness,and the character of dynamic behavior for electron beam focus was analyzed.The effects of welding speed and work distance on the dynamic behavior of the focus also were studied.The results show the critical penetrating currents increase compulsorily and the curve of the focus behavior shifts up with the enhancement of welding speed.The dynamic focus shifts down with the increase of work distance.The increase ... |
