Beschreibung
Zusammenfassung:	The utility model discloses a friction stir welding tool which comprises an electromagnet suction cup, a silica gel heating plate and a pressing plate. The electromagnet suction cup is used for sucking a bottom plate to be welded. The silica gel heating plate is placed between the electromagnet suction cup and the bottom plate and used for heating the bottom plate. The pressing plate is placed on the silica gel heating plate and used for flattening the bottom plate. According to the friction stir welding tool of the structure, a bottom plate to be welded is placed on the silica gel heating plate, then the electromagnet suction cup is started to suck the bottom plate, then the pressing plate is used for pressing the bottom plate from the upper portion, the silica gel heating plate can heat the bottom plate, and the friction welding procedure is conducted on the heated bottom plate. The heated bottom plate can reduce deformation caused by thermal stress in the friction welding process due to thermoplasticity, t
