ABSTRACT
Friction stir welding (FSW) is a solid state joining process used to join metals and their alloys. The main goal of this paper is to select the optimal welding parameters such as: rotational speed and the feed rate of the tool. The article presents the results of the tests on welding 1mm thick 2024 aluminum sheet according to the statistical 3-level completed plan PS/DK32. The rotational speed of the tool varied within the range of 1100 ÷ 1300 rpm and the feed rate within the range of 40 ÷ 60 mm/min. For these parameters the analyses of the experiment repeatability, impact significance and adequacy of equations were made.
