    • PURPOSE: A friction stir welding device is provided to preheat or cool a welding tool by supplying preheating air or cooling air to the welding tool. CONSTITUTION: A friction stir welding device comprises a rotary member(10), a vortex tube(50), a preheating gas feeding unit(70), and a cooling air feeding unit(90). The rotary member has a welding tool(15). The welding tool presses the joint parts of base materials and generates frictional heat. The vortex tube is connected to the rotary member and supplies preheating air or cooling air to the inside the welding tool. The preheating gas feeding unit supplies preheating gas to the vortex tube. The cooling air feeding unit supplies cooling air to the vortex tube.
    • 目的:提供摩擦搅拌焊接装置,通过向焊接工具提供预热空气或冷却空气来预热或冷却焊接工具。 构成:摩擦搅拌焊接装置包括旋转构件(10),涡流管(50),预热气体供给单元(70)和冷却空气供给单元(90)。 旋转构件具有焊接工具(15)。 焊接工具按压基材的接合部分并产生摩擦热。 涡流管连接到旋转构件,并向焊接工具内部提供预热空气或冷却空气。 预热气体供给单元向涡流管供给预热气体。 冷却空气供给单元向涡流管供给冷却空气。
