摘要
搅拌摩擦焊的高效焊接问题一直是研究的焦点。对影响高效搅拌摩擦焊技术的关键因素(焊接工装、搅拌工具和焊接工艺)进行系统阐述并提出优化设计方案。结果表明,采用真空吸盘可以有效提高装卡效率,减少焊接装配时间;采用双重水冷系统和粉末冶金材料制造的搅拌工具,其有效寿命达2000m;通过优化焊接工艺,能够有效实现焊接速度1 000 mm/min的高速搅拌摩擦焊接技术,获得了最高抗拉强度接头系数为76.5%,最高屈服强度为164 MPa的焊接接头。
The key factors ＇affecting the efficiency such as welding equipment,friction tool and Welding process were elaborated ,and Optimization programs were proposed. The results show that,the system of vacuum suction is adopted,which can improve efficiency of welding and reduce the assembly time. Double water-cooled structure and Powder metallurty materials which can improve the quality are employed in the design of FSW tool,and the life of FSW tool can be 2000m. High speed welding that wehting speed can reach 1 000 mm/min can comprehend. The maximum joint coefficient of strength tensile was76.5%,and the highest yield strength was 164 MPa.
