铺设无缝线路,要求两股焊接长钢轨铝热焊缝相对问题,目前有两种不同意见: 一种认为,两股钢轨的铝热焊缝必须相对,其允许相错值与普通有缝线路接头要求同。由于铝热焊接技术的关系,焊缝处的平顺性没有钢轨的平顺性好,个别焊缝对机车车辆和对线路所产生的影响并不次于有缝线路的接 There are currently two different opinions regarding the relative problems of laying two weld lines on a long rail aluminum hot weld: one is that the hot weld of the two rails must be opposite, which allows the phase error value to be normal Line connectors require the same. Due to the aluminum heat welding technology, the smoothness of the weld does not have the good smoothness of the rail. The influence of individual welds on rolling stock and on the line is not inferior to that of the seam line
