The invention discloses a friction welding semi-grouting sleeve. The friction welding semi-grouting sleeve comprises a sleeve grouting section and a sleeve threaded section, the pipe wall end face of the sleeve grouting section is in direct contact with the end face of the sleeve threaded section, and the sleeve grouting section and the sleeve threaded section are fused and connected through friction welding to form an integrated structure. A groove and circular truncated cone interlocking mode is not needed in the sleeve threaded section, and the machining cost is saved; welding materials are not needed, welding seam filling is avoided, and the raw material cost is saved; the welding seam quality after friction welding is high, the conventional welding seam defect problem is solved, and the joint firmness is superior to that of conventional welding and threaded connection; high-quality welding between different materials can be achieved, optimal combination of the materials of the sleeve grouting section and the sleeve threaded section is facilitated, the material cost is reduced, and meanwhile, the combination of exerting the maximum mechanical performance of the different materials is achieved; and energy conservation and environment protection are achieved, the friction welding efficiency is high, and automatic production of products is easy to realize.
本发明公开一种摩擦焊半灌浆套筒，包括套筒灌浆段和套筒螺纹段，所述套筒灌浆段的管壁端面与所述套筒螺纹段的端面直接接触，所述套筒灌浆段和所述套筒螺纹段通过摩擦焊融合连接形成一体结构；在套筒螺纹段无需坡口及圆台互锁方式，节约了加工成本；无需焊材，无焊缝填充，节约了原料成本；摩擦焊后的焊缝质量高，不会出现常规焊缝缺陷问题，接头牢固性能优于常规焊接与螺纹连接；可实现不同材质之间的高质量焊接，利于套筒灌浆段和套筒螺纹段的材料优化组合，降低材料成本，与此同时，实现了发挥不同材料的机械性能最大效用的组合；节能环保，摩擦焊接效率高，易实现产品的自动化生产。
