description: The topic of the qualification work is: Â«Influence of the parameters of the refill friction stir spot welding on the macrostructure and properties of the materialÂ». This work is devoted to the study the method of refill friction stir spot welding of AA 6061-T6 on macrostructure and properties. The work was carried out at Peter the Great St. Petersburg Polytechnic University, in the laboratory "Research and modeling of the structure and properties of metallic materials". The analysis of the dependence of the structure of the weld joint on the choice of welding speed was carried out. The resulting welded joints were subjected to metallographic analysis and microhardness measurements. The regularities of obtaining a defect-free welded joint. The relevance of the use of refill FSSW was determined.
