Abstract：The article describes the burning fault of brake components by excessve electricity existing in the welding process of railway freight cars，introduces the welding principle，describes the fault simulation test and analyses the cause of fault，and mainly analyses the impact of different welding wiring positions on the burning fault of braking components. It analyses the risk according to the working principle of the relief valve and the decomposition and inspection of the burning condition，plans and verifies the risk acording to the occurrence rate of burning，and finally proposes suggestions for optimization and improvement.

Key words： railway freight car; braking component; welding process;analysis of impact

铁路运输是国民经济稳定运行的重要保障，在铁路货车的制造、检修过程中，焊接技术是极其重要的一个组成部分，但个别车辆在经过修焊或点焊后会发生制动部件故障。（剩余6336字）
