钢轨铝热焊接技术已广泛地应用于行车轨道的焊接,用来消除由于轨道之间的缝隙而产生的行车轮轨严重冲击和过度磨耗,以及运行过程中产生的行车突然振动和轨道变形等问题。根据现场焊接施工经验,总结了从焊接接头外观、平直度及硬度进行检验行车轨道钢轨铝热焊接接头的方法与要求。
Rail aluminum heat welding technology has been widely used in the welding of the running track to eliminate the severe impact and excessive wear of the running wheel track caused by the gap between the tracks and the sudden vibration of the running track and deformation of the track caused by the running process . According to the experience of on-site welding construction, this paper summarizes the methods and requirements for inspecting the aluminum heat welded joints of the rail of the driving rail from the appearance, flatness and hardness of the welded joints.
