客运专线钢轨焊接采用基地焊(或厂焊),钢轨矫直、对中、精磨等手段齐全,可以有效保证焊接接头质量。25~100 m定尺轨在线上直接采用移动式闪光焊与基地固定式闪光焊比较,质量有一定差距。线上长轨条焊接可采用铝热焊、气压焊或移动式闪光焊(焊机带保压推凸功能)。100 m定尺钢轨焊接生产线应采用U形串列式布局,降低生产线长度,将生产线总长度缩短到1 000 m以内。
Passenger Dedicated rail welding using base welding (or factory welding), rail straightening, alignment, grinding and other means complete, you can effectively ensure the quality of welded joints. 25 ~ 100 m fixed-size rail directly on the line using mobile flash welding and base fixed flash welding comparison, the quality of a certain gap. Long line welding can be used aluminum hot welding, pressure welding or mobile flash welding (welder with pressure push convex features). 100-meter-long rail welding production line should be U-shaped tandem layout, reducing the length of the production line, the production line will be shortened to less than 1 000 m in length.
