摘要：
A system and method for using Friction Stir Spot Joining (FSSJ) to join workpieces made of Advanced High Strength Steels (AHSS), wherein a first embodiment is a FSSJ tool that has no surface features, and wherein the rate of rotation of the FSSJ tool is much higher than is used in other FSW techniques to thereby reduce torque by causing plasticization of the AHSS on a small scale, and in a second embodiment, conventional FSSJ tools can be used at conventional FSSJ speeds if the FSSJ tool is manufactured from conductive tool materials having a high hardness, and heating of the FSSJ tool and/or the workpieces enhances the ability of the FSSJ tool to functionally weld the AHSS.
摘要（中）：
一种使用摩擦搅拌点连接（FSSJ）来连接由先进高强度钢（AHSS）制成的工件的系统和方法，其中第一实施例是不具有表面特征的FSSJ工具，并且其中FSSJ工具的旋转速率 远高于其它FSW技术中所用的，从而通过使小规模的AHSS塑化来减小转矩，并且在第二实施例中，如果FSSJ工具由导电工具制造，则常规FSSJ工具可以常规FSSJ速度使用 具有高硬度的材料以及FSSJ工具和/或工件的加热增强了FSSJ工具在功能上焊接AHSS的能力。
