This series use screws to compress the work pieces. The welding process is finished under the reasonable current gear and upset force in the man-controlled time.

该系列对焊机采用螺杆压紧工件，选择合适的电流档位和顶锻力，人控焊接时间完成焊接过程。

The results show that the upset force increases with the increasing of the upset length and upset speed, and increases with the reducing of the heating temperature.

结果表明：钢轨焊接所需顶锻力随顶锻量、顶锻速度的增加而增大，随焊口温度的降低而升高。

This would wreck budgets and upset the navy and air force.
