Background
Friction Stir Welding (FSW) is a solid phase joining technique invented by british institute of Welding (US5460317) in 1991, and is particularly suitable for Welding low melting point alloys such as aluminum. Friction stir welding utilizes friction heat generated by friction between a shaft shoulder and a stirring needle and a workpiece to enable materials near a welding joint to reach a plastic state, the material flowability is increased, when a stirring head moves forwards, the plasticized materials are moved to the rear of the stirring head under the extrusion of the shaft shoulder and the stirring action of the stirring needle, the materials are cooled to form the welding joint, the materials are not melted in the welding process, and the highest temperature is about 80% of the melting point of the welded materials. Compared with connection methods such as fusion welding, brazing, riveting and the like, the technology has the advantages of low heat input, small deformation, cleanness, no pollution, higher weld strength and the like, and is widely applied to the industries of aerospace, rail transit, ships, automobiles, power electronics, weapon manufacturing, buildings, electricity and the like. With the advancement of technology and the gradual improvement of supporting facilities, the research and application of friction stir welding are entering a rapid development stage.
The great success of FSW technology in the field of aluminum alloy structure manufacture has led to a desire for its application in various weld joint forms and joining of metallic materials. However, most of the industrial applications of the FSW technology are mainly limited to the simple butt joint form, and are limited by the shaft shoulder of the stirring tool when applied to T-joints, fillet welds and box-shaped structures which are used in large quantities in the manufacture of structures such as aircraft fuselages, ship decks, automobile and train bodies, and the like, and the FSW technology is difficult to be applied to the manufacture of the structures; when the FSW technology is popularized and applied to welding of low-heat-conduction materials such as titanium alloy, due to the friction heating effect (generating 70-80% of most heat) of a shaft shoulder of a stirring tool and a welded surface, the surface of a welding seam is overheated and the temperature along the thickness of the plate is obviously uneven, so that a defect-free welded joint is difficult to obtain.
In order to overcome the limitation of the traditional FSW technology, the shaft Shoulder and the stirring pin are separated on the basis of the traditional FSW technology, and a static Shaft Shoulder Friction Stir Welding (SSFSW) technology is developed; the method not only can effectively realize the welding of low heat conduction materials such as titanium alloy and the like, but also has obvious advantages in the manufacture of aluminum alloy fillet welds and T-shaped welding joints.
