【 摘 要 】

Friction Stir Spot Welding is one of the most contemporary methods of joining metals and alloys in their solid state. The ability to join elements made of aluminum alloys allows for utilizing this method in the manufacturing of aircraft structures while lowering the work load, costs, and weight, without sacrificing or even having better strength parameters than classic methods of joining elements. It ensures constant joint parameters, however it requires the use of optimal welding parameters such as: the rotational speed of the tool, tool delve depth, and welding time. The work presents the results of experiments conducted on 7074 aluminum sheet metal that was 1.8 and 0.8 mm thick, which conducted in accordance with the PS/DK32 research plan. The welding tests were done on a dedicated spot welding machine, while the strength tests consisted of static tensile strength tests. In the final part of the article contains an analysis and interpretation of the results
