本文从力学的角度，用解析的方法研究了搅拌摩擦焊(FSW)过程中的预浸泡阶段。这一初始阶段是实际工艺过程的一部分，当FSW仪器到达与工件的接触点时，预热接触区，但不会穿透材料。这种方法能够在一定程度上洞察FSW过程，其中系统参数是已知的，并且理论结果的实验评估是可能的。此外，还给出了仪器平行旋转和平移过程中干摩擦和粘性摩擦功率输入的解析估计。对这些现象进行了研究，包括搅拌摩擦焊机与工件之间的摩擦。研究了干摩擦和粘性摩擦的影响。通过实验对计算结果进行了验证。
In this paper, the investigation of a pre-immersion period of Friction Stir Welding process (FSW) from the mechanical point of view using analytical considerations is presented. This initial period is a part of the real technological process, when a FSW instrument reaches the touchdown point with the workpiece, preheats the contact zone, but does not penetrate the material. This approach enables an insight into FSW process on a level, where the system parameters are known and an experimental evaluation of theoretical results is possible. Beside these considerations an analytical estimation of the power input of dry and viscous friction during instrument rotation and translation in parallel is shown. These phenomena are investigated including friction between a FSW instrument and a workpiece. The influences of both dry and viscous friction are studied. Experiments have been done to validate the calculated results.
