由于钢轨接触焊接头灰斑与性能受众多参数综合影响，故采用正交设计安排试验。

Because of that both the grey spots and the performances of the rail resistance welding joints are under the synthetical influence of many parameters, the orthogonal design was used to settle tests.

影响钢轨闪光焊接头焊接质量的因素很多，其中焊机动力柱的送进速度就是重要因素之一。

The feeding speed of shifting unit of welding machine is one of the most important factors of rail continuous flash welding quality.
