Compared with as-welded specimens with no defects, the fatigue strength has been increased by 32%, and the fatigue life by 2~7 times.

与不含焊接缺陷的焊态试件相比，提高疲劳强度32%，提高疲劳寿命2～7倍；

The results show that the weldments made from those metals in as-welded condition are instable in dimension and the rate of dimensional change decreases with time.

结果表明：七种材料的焊件都存在着尺寸不稳定，这种尺寸不稳定变形随时间的变化速率逐渐变缓；

Finally, the welding procedure has been proved to be feasible by as-welded appearance checking, magnetic powder inspection, ultrasonic inspection and radiographic inspection.

最后，本课题通过焊后的外观检测、磁粉探伤焊、超声探伤和射线探伤证明了焊接工艺规范合理可行。
