摘要: |
采用MIG堆焊方法在30CrMnSi活塞上堆焊铜合金来代替导向环,通过理论分析、接头宏观检验及油缸试验等方法,得到了合理的工艺参数及工艺流程。采用该工艺参数及工艺流程,成功解决了堆焊铜导向环划伤缸筒的问题,得到一种在特殊结构活塞上功能相当于标准导向环的焊层。 |

Abstract: |
The guide ring is replaced with the copper alloy welded on the piston by the MIG surfacing method. The reasonable technological parameter and technological process are obtained through the theoretical analysis, the macroscopic examination of joint and the test of oil cylinder. Using the method, the problem that cylinder barrel is scratched by the guide ring of welding copper is resolved. A welding layer is acquired which amounts to the normal ring on the function of the special structure joint. |
