| 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. |
