搅拌摩擦微连接设备及工艺研究

Research on the equipment and process of micro friction stir welding

由于已在航空航天及电子领域广泛应用的铝、镁合金难以实现超薄板焊接,研究设计了基于Mach3软件控制系统的搅拌摩擦微连接焊机。利用该设备进行焊接作业,宜采用轴肩直径为6～8 mm的搅拌工具针对厚度在1 mm内的薄板进行施焊,且可进行3D成型搅拌摩擦微连接,焊接热输入、焊件变形小,焊缝成形美观。Mach3软件控制系统具有优秀的兼容性、可操作性和稳定性,操作简单、维护方便并具有开放性,搅拌摩擦微连接焊机体积小、质量轻、安装方便,焊机整体稳定性高、可操作性强。

Because aluminum and magnesium alloys,which have been widely used in aerospace and electronics,are difficult to achieve ultra-thin plate welding,a micro friction stir welding machine based on Mach3 control system was designed. For the welding operation using this equipment,the stirrer with a shoulder that diameter was 6~8 mm could be used for the welding of thin plates(≤1 mm),and the 3 D forming micro friction stir welding could be completed. There was a small amount of heat input in the welding process,small deformation occurred and the appearance of weld was great. The Mach3 control system is excellently compatible,applicative,and stable.It is easy to operate,maintain and open. The micro friction stir welding machine is small in size,light in weight and easy to install. The welding machine is available with high welding stability and operability.
