| Abstract: | The authors describe the material status of hollow axle sleeve in DFll and DF4D （quasi-high speed） diesel locomotives, and give correct understandings on the materials. The authors suggest the suitable welding consumables used for the welding repair of hollow axle sleeves of these two types of locomotives. Meanwhile, welding procedure test and mechanical properties of welded joints test are both carried out, the test results show that the post-welding performance of the selected welding consumables meets the requirements. |
