由于货车运用强度的日益提高,цнии-X3-0转向架减振器零件(平铁和斜铁)的磨损增大了,从而导致堆焊工作量的增加。车辆修理工厂所采用的пп-AH3或пп-ни14гст-T-C管状焊丝半自动堆焊,因效率不高以致在不增加焊工的情况下就不能保证修理计划的完成。因此,最好采用如金属颗粒之类的辅助焊料进行堆焊。全苏铁路运输科学研究院乌拉尔分院与斯维尔得洛夫车辆段合作研究出使用辅助焊料,即在球磨机内经过碾碎处理的切屑来堆 Due to the increasing use of trucks, the wear and tear on цнии-X3-0 bogie suspension parts (flat iron and wedges) has increased, resulting in an increase in the amount of work to be done. Semi-automatic welding of пп-AH3 or пп-ни14гст-T-C tubular welding wire used in vehicle repair factories is not efficient enough to ensure the completion of the repair program without increasing the number of welders. Therefore, it is best to use auxiliary particles such as metal particles for surfacing.
