摘要： A friction agitation welding apparatus comprises a threaded shaft (46) fixedly connected to a motor shaft, a slide housing (48) in engagement with the threaded shaft (46) for vertical movement, a first drive shaft (58) supported for rotation by but coupled fixedly in axial movement to the slide housing (48) and equipped with a friction agitation welding tool (4), and a second drive shaft (64) fixedly connected to a motor shaft and telescopically supported by but coupled fixedly in relative rotation to the first drive shaft (58), moves to advance the friction agitation welding tool (4) to urge superposed workpiece to be joined. When the second drive shaft (64) is rotated, the first drive shaft (58), and hence the friction agitation welding tool (4), rotates even while the friction agitation welding tool (4) urges the superposed workpieces.

摘要： A projection (3) is pressed into first and second members (W1) and (W2) with a predetermined pressure, while rotating a rotary tool (1) at a preset rotational speed, such that the first and second members (W1) and (W2) are sandwiched by the rotary tool (1) and stationary tool (10). The projection (3) rotates in these members (W1, W2) to cut member textures around it, thereby generating heat. Furthermore, the cuttings formed by cutting with the projection (3) are accumulated in the members (W1, W2) and agitated by the two tools (1) and (10), to collide against the surrounding member textures and the projection (3), thereby generating heat. Also, a first shoulder (2) is pressed in with a predetermined pressure and rotated to generate heat, thereby fusing the cuttings. While the plastic flow of the surrounding member textures is promoted, the first shoulder (2) is held at the predetermined pressure and rotational speed.

摘要： A projection 3 is pressed into first and second members W1 and W2 with a predetermined pressure, while rotating a rotary tool 1 at a preset rotational speed, such that the first and second members W1 and W2 are sandwiched by the rotary tool 1 and stationary tool 10. The projection 3 rotates in these members to cut member textures around it, thereby generating heat. Furthermore, the cuttings formed by cutting with the projection 3 are accumulated in the members and agitated by the two tools 1 and 10, to collide against the surrounding member textures and the projection 3, thereby generating heat. Also, a first shoulder 2 is pressed in with a predetermined pressure and rotated to generate heat, thereby fusing the cuttings. While the plastic flow of the surrounding member textures is promoted, the first shoulder 2 is held at the predetermined pressure and rotational speed. The pressure per unit area is thus increased to increase the volume of plastic flow. When the rotary tool is pulled out while being rotated, the member textures that have been plastically flowing are cooled and joined to each other.
