Description of the Invention: [Technical Field] The present invention relates to a friction stir welding tool, and more particularly to a method in which a plurality of rings are disposed outside the edge of a burr blade, and the outer ring side pin is firstly The material relies on reducing the resistance of the thread cutter during the welding process and reducing the tool wear. [Prior Art] • In the process of precision machining of a machine, in order to fuse two metal plates together, the metal plates are usually brought close to each other, and a mixing tool is placed on the adjacent sides of the two metals. As shown in the figure, where the 'grinding tool' is made of high-speed steel and has a 2^ system at the end, the mixing tool will rotate around itself and rotate along the adjacent sides of the two metal plates. Advancing, the stirring head is agitated to the metal plate, and the adjacent sides of the metal plates are heated by friction to cause plastic flow, and the metal plates are joined together. Referring to Figures 2, 3 and 4, The schematic diagram of the cross-section metallographic phase of the front-end cross-section of the rubbing and splicing of the Lulu is shown in the figure. The main feature of the Huidao is that the mixing zone has a Yanghui ring structure, and many strip-shaped structures can be found in the strip-shaped structure. The crystal grains 'and the crystal size in the weld bead are about 2G-30_. ^Friction Stir Welding (FSW) is the use of the tool = material inside to make the material produce severe plastic deformation, the joint material ^ 2 'the heat generated by the splicing process to change the tool geometry, with Drying increases the tool wear problem more seriously. Especially used in the joint material base material, the composite material towel is hard and crispy, and the hardness is higher than that of the metal mixing tool. During the welding process, the tool is not only affected by the friction heat 3 201226092 The weight is οσ Strict 3' strengthening particles And the tool. The friction (4) makes the tool wear more. [Invention] The disadvantages of the above-mentioned prior art are that the friction-winning welding material 1 of the present invention is reduced, thereby achieving the reduction of the tool = the first and the material resistance. Another object of the invention is to provide a frictional splicing cutter according to the present invention, which is provided with the outer ring side pin and the material contact, so that the dry contact is contacted and the abrasion is started, thereby achieving the lifting of the lake; The combined section, the movable joint on the joint section - the replacement knife 2: The head phase county section - the end set has a - lion head, the master has a thread cutter and a plurality of sets. The side pin is suitable for mixing, and the outer ring side pin is firstly contacted with the material. At this time, the material ring=ring side pin and the reinforcing particle first-time contact start to wear, and the second and second liter materials are generalized, and the tool is welded. Reduced financial resources and reduced tool wear. /, 枓 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上 以上Other objects and illustrations of the invention are set forth.

Please refer to FIGS. 5 and 6 , which are schematic diagrams of the friction-dissipating fresh-connecting tool of the present invention. As shown in the figure, the friction stir welding tool comprises a body 1 having a front end and a rear end, and the front end of the ship is - a joint section having a (four) pattern on the joint section - a replacement cutter head 2 having a fixed shaft hole,
