钢轨铝热焊与其他焊接方法相比,具有所用设备简单、操作方便、接头平顺性高、作业时间短、焊接占用空间小和占用工程时间短等特点,基本满足了高速和重载铁路线路接头高性能和作业短流程两个特点,但仍然存在一些问题和不足。在进行钢轨焊接时,应针对所焊钢轨的性能,确定与之相匹配的焊缝性能。影响焊缝性能的因素是多方面的,从焊缝中的主要元素和合金元素等对焊缝性能的影响作了分析,并提出了控制各元素含量的对策、措施。
Compared with other welding methods, the rail aluminum hot welding has the characteristics of simple equipment used, convenient operation, high smoothness of joints, short operation time, small welding occupation space and short construction time, and basically meets the requirements of high speed and heavy load railway line joints High performance and short process two characteristics, but there are still some problems and deficiencies. In the rail welding, the performance of the welded rail should be determined to determine the performance of the weld. The factors affecting the performance of the weld are many, from the weld of the main elements and alloying elements on the performance of the weld were analyzed, and put forward the control of the elements of the countermeasures and measures.
