    • A friction stir welding apparatus and a method of operating the friction stir welding apparatus are disclosed. The friction stir welding apparatus includes a rotary tool whose extremity constitutes a probe, a retaining arm which supports the rotary tool, and a roller provided at a position of the retaining arm opposite the rotary tool. The method includes adjusting the retaining arm so as to position workpieces between the rotary tool and the roller while adjusting the roller to turn in a direction where a joint line of the workpieces extends, rotating the rotary tool and lowering the probe until the probe presses the workpieces, gradually inserting the probe into the joint line, and moving the probe along the joint line.
    • 公开了一种摩擦搅拌焊接装置和操作摩擦搅拌焊接装置的方法。 摩擦搅拌焊接装置包括旋转工具,其末端构成探针,支撑旋转工具的保持臂和设置在与旋转工具相对的保持臂的位置处的辊。 该方法包括调节保持臂,以便将工件定位在旋转工具和辊之间,同时调节辊沿着工件的接合线延伸的方向转动,旋转旋转工具并降低探针直到探针压紧 工件,将探头逐渐插入接合线,并沿着接合线移动探头。
