| Abstract: | The sixth section of Lanzhou ~ Urimqi second double track railway line in Xinjiang covers some 650 km track-laying in terms of single track. 60 kg / m U71Mn( G) rail is used for CWR. In order to guarantee the quality and improve the efficiency of rail welding,YHG-1200 TH flash-butt welding machine is employed. The paper introduces the functions and performances of the machine,the methods for selecting welding parameters and quality examination. The rationality and validity of the selected welding parameters are proved experimentally. |
