无砟轨道现场闪光接触焊钢轨焊头平直度的控制

On control over smoothness of spark contact welding head at ballastless rail sites

介绍了无砟轨道现场闪光接触焊接方法的应用现状,从闪光接触焊机对轨精度、粗磨工艺、正火及调直过程等方面,分析了影响现场闪光接触焊钢轨焊头平直度的因素,并提出了具体的控制措施,以保证焊接工程的质量。

The paper introduces the application of the spark welding method on the ballastless rail sites,analyzes the factors affecting the smoothness of the welding head on the sites from the rail accuracy,coarse grinding,normalizing and straightening process,and points out the controlling measures,so as to ensure the quality of the welding projects.
