| 摘 要： | 直尺+塞尺法测量焊接接头平直度有一定的局限性,有时不能真实反映焊接接头的实际平顺程度。采用SEC(Straight Edge Compact)电子平直尺(仪)测量钢轨焊接接头平直度,通过分析1m范围内的平直度曲线,得出4种典型曲线。根据不同类型的平直度曲线,可找出造成超差的原因,并制定出有效的改进焊接和打磨工艺措施。

Method of Measuring the Flatness of Rail Welding Joint and the Analysis |
| |
| Abstract: | The method of ＂ruler ＋ feeler gauge＂ has some shortcomings when it is used to measure the flatness of welding joint, sometimes this method could not reflects the actual flatness of the welding joint. SEC electronic ruler is adopted to measure the miness of welding joint. By analyzing the flatness curves within 1m, 4 types of typical curves are gained. According to different types of flatness curves, the causes of errors could be found and effective improvement measures for welding and grinding could be formulated. |
