AMS60钢轨交流闪光焊机焊接工艺研究

Study on the technology of AMS60 movable AC flash butt welding machine

由于AMS60移动式钢轨交流闪光焊机焊接回路长,具有较大的回路阻抗,相对于К系列钢轨交流闪光焊机而言,其短路焊接电流小,焊接电流上升速度慢,焊接工艺调节困难。针对AMS60焊机这些特点,对U71Mn钢轨进行了焊接工艺研究,得到了适合其特点的焊接工艺参数,通过了铁标规定的工艺试验,并已在工程实际中得到应用。

The AMS60 movable AC flash butt welding machine has a long welding circuit with and high circuit resistance,so it is of small short welding current and slow di/dt,and it’s difficult to adjust the welding procedure as comparing to Кseries AC flash butt welding machine.Aiming at behavior of AMS60,the research was finished based on U71Mn rail,and the appropriate welding process parameters have been found to past the technological test of TB and has been used in practical application.
