自上世纪九十年代,我国开始铺设跨区间无缝线路,当时沈阳、北京等铁路局既有线现场焊接采用气压焊接方法进行锁定焊接作业,随着铝热焊接技术的进步,有些路局采用铝热焊方法进行锁定焊接。而移动式闪光焊接正式用于现场联合锁定焊接,国内各铁路局还没有先例。
Since the nineties of last century, China began to lay a cross-section of seamless lines, when Shenyang, Beijing and other existing railway line on-site welding using pressure welding method for locking welding operations, with the aluminum thermal welding technology advances, Aluminum hot welding method for locking welding. The mobile flash welding officially used for joint lock-site welding, the domestic railway bureau has no precedent.
