无缝铁路铺设的最重要的环节是钢轨焊接,目前主要采用的焊接方式有铝热焊、闪光焊和气压焊。小型气压焊轨机曾在无缝铁路的焊接和铺设中起到了重要的作用,但是由于其设备的局限性,使其应用范围受到限制。YHGQ-1200型大型气压焊轨车是目前世界上唯一的先进成套设备,适应各种恶劣环境的焊轨作业,弥补了原有小型焊轨机的不足。本文将从材料、设备、生产成本等方面对比移动式大型气压焊轨车和小型手动气压焊机,充分展现气压焊轨车的行业优势。
The most important part of seamless railway laying is rail welding. At present, the main welding methods are aluminum thermal welding, flash welding and pneumatic welding. Small air-pressure welding machines used to play an important role in the welding and laying of seamless railways, but their range of applications has been limited by the limitations of their equipment. YHGQ-1200 large-scale pneumatic welding rail car is the world’s only advanced complete sets of equipment to adapt to a variety of harsh environment welding track operations to make up for the deficiencies of the original small welding machine. This article compares the mobile large-scale air pressure rail car with the small manual air pressure welding machine from the aspects of material, equipment and production cost to fully reveal the industry advantages of the air pressure rail car.
