2195铝锂合金的补焊工艺OA北大核心CSTPCD
The investigation on repair welding technology of 2195 aluminum-lithium alloy
采用两种焊接速度(800 mm/min和180 mm/min)的TIG焊对2195铝锂合金焊缝缺陷进行修补,通过接头的力学性能、金相组织和断口形貌对补焊效果进行对比和分析.指出了补焊速度对补焊接头气孔敏感性、氧化敏感性和机械性能的影响,同时也讨论了多次补焊对焊接接头性能的危害.
High strength 2195 aluminum-lithium alloy was repaired by TIG arc welding.The mechanical properties, microstructure and fractography of welded joints was observed and analyzed.The comparison and analysis of the two welding speed' s (800 mm/min and 180 mm/min respectively) repairing effect has been made and the affect of repair welding speed to stomatal sensitivity, oxidation -sensitive and performance of welded joints have been researched.And also discussed …查看全部>>
