In the 48 days from June 20 to August 6, Aigre UN5-150ZB flash welder completed the whole track welding operation of Shanghai-Hangzhou high-speed railway with good quality and quantity. On Sept. 28th, 2010, the Beijing-Shanghai high-speed railway set a world record for the highest speed of trial operation, with the train’s maximum speed reaching 416.6 km/h. This moment was remembered by all the staff of Aigre, who made the UN5-150ZB flash rail welding machine.

Professor Lv qibing of southwest jiaotong university spoke proudly that when Chinese companies purchase the rail welder, they will first choose Aigre. At present, the UN5-150 series welding machines have been successfully exported to South America, South Asia and other countries and regions.
