摘要
介绍DF11和DF4D准高速型内燃机车空心轴套的材质状态和对材质的正确理解,提出适合这2种车型的空心轴套焊修时所应采用的焊材型号,同时进行了焊接工艺试验和焊接接头力学性能测试,试验结果表明,所选焊材的焊后性能符合要求。
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.
