Problems solved by technology

[0005] At present, the existing stopper rod structures for repair welding of aluminum alloy plugs mainly include smooth cylinders, ordinary cylindrical threads, tapered threads, large groove threads and threads with spiral flow grooves, etc., and the welding thickness is less than 40mm. However, with the popularization and application of aluminum alloy plug repair welding, the existing stopper rods have been unable to achieve the welding of aluminum alloy plates with a thickness exceeding 40 mm.

Abstract

The invention relates to a novel aluminum alloy plugging rod for plug welding. The novel aluminum alloy plugging rod for plug welding comprises a conical plugging rod body. Three straight edge surfaces are uniformly distributed on the conical plugging rod body in the length direction of the conical plugging rod body. A conical surface is formed between every two adjacent straight edge surfaces, and three conical surfaces are formed and provided with different spiral grooves respectively, namely, the annular spiral grooves, the left-handed spiral grooves and the right-handed spiral grooves. By means of the novel aluminum alloy plugging rod for plug welding, the welding thickness can be greatly increased to 100 mm from original 40 mm, heat generated by friction is more uniform, material flowing is more reasonable, and the quality of weld joint products is better.

Description

technical field [0001] The invention relates to the machinery industry, in particular to a novel stopper rod for repairing welding of aluminum alloy plugs. Background technique [0002] Friction stir welding is a solid-state joining method proposed by The Welding Institute (TWI) in 1991, and applied for intellectual property protection in developed and developing countries around the world in 1993 and 1995. The principle of this technology is simple, and there are few control parameters, which is easy to automate and can minimize the human factors in the welding process. Compared with traditional fusion welding, friction stir welding technology has many advantages, which makes it have a wide range of industrial application prospects and development potential. Research on the structure, mechanical properties (including fracture, fatigue and corrosion properties) of friction stir welded joints, non-destructive testing and the influence of process parameters on weld quality is...
