转向架制造技术,是高速动车组的九大核心技术之一。我国的高速动车组之所以能跑出如此高的速度,其主要原因之一就是转向架技术取得了重大突破。在转向架制造过程中,转向架环口焊接是最关键的工序之一。李万君就工作在环口焊接的岗位上。李万君是中国北车长春轨道客车股份有限公司的一名员工。按照铁道部要求,转向架每一条焊缝都必须经过超声波检测和射线探伤,绝不允许有一点瑕疵。“严苛”的质量标准,造就了李万君的“精细”品质,在他手中,
Bogie manufacturing technology, high-speed EMU is one of the nine core technologies. One of the main reasons why China’s high-speed EMUs can run such a high speed is that the bogie technology has made a major breakthrough. In the bogie manufacturing process, the bogie ring welding is one of the most critical processes. Li Wanjun work in the ring welding position. Li Wanjun is an employee of CNR Changchun Railway Vehicles Co., Ltd. According to the requirements of the Ministry of Railways, each weld of the bogie must undergo ultrasonic inspection and radiographic inspection, and no imperfection is allowed. “Harsh ” quality standards, created Li Wanjun “fine ” quality, in his hands,
