一种新型国产分体式搅拌摩擦焊搅拌头工艺研究与分析

Research and Analysis of A New Type Domestic Split Friction Stir Welding Mixing Head

针对直圆柱体结构分体式搅拌摩擦焊搅拌头容易引起卡刀柄的问题,现对其结构进行优化,设计了一种带止挡台的新型国产分体式搅拌摩擦焊搅拌头。以6005A铝合金为研究对象,研究了优化后搅拌头旋转速度、焊接速度等不同焊接工艺参数对接头质量的影响,得出最优的焊接参数,为后续的生产提供理论依据。

Aiming at chucking handle problem of splitting friction stir welding stirrer head with straight cylinder structure, the paper discusses structure optimization, and designs a new domestic splitting friction stir welding stirrer head with stopper. Taking6005 A aluminium alloy as research object, the paper researches effects of different welding parameters of optimized stirring head,such as rotating speed and welding speed on joint quality, to obtain optimal welding parameters, to provide theoretical basis for subsequent production.
