The article discusses the basic issues related to the technology of friction stir welding (FSW). A short description of technology is provided. The following section provides the analysis of effect of technological parameters (tool rotation and welding speed) on the mechanical properties of the prepared joint (strength, ductility, microhardness). In both cases the analysis refers to aluminum alloys (6056 and AA2195-T0). The comparative analysis showed the phenomenon of the increase in weld strength along with the increase in the rotational speed of the tool during welding. Similarly, with the increase in welding speed, an increase in weld strength was observed. Some exceptions have been observed from the above relations, as described in the article. In addition, examples of material hardness distribution in the joint are presented, indicating their lack of symmetry, caused by the rotational movement of the tool. The analyses were performed basing on the literature data.

Friction stir welding (FSW) as a solid state joining process is being known recently by many industries due to its capability to reduce defects, energy efficient, and environment friendly compared with conventional techniques. Specifically, FSW can be used to join highstrength aluminum alloys like 7XXX and 2XXX which are hard to weld by conventional fusion welding. In this review paper, the elementary principles of FSW, parameters, and the effect of the FSW parameters on microstructure and mechanical properties are addressed. Although this process has a lot of advantages compared with fusion techniques, however, many problems still remain unsolved related to poor mechanical properties of weldment's heat affected zone (HAZ). In this regard, the impact of post weld heat treatment (PWHT) on improvement of joint properties is addressed. Finally, appropriate parameters and factors for achieving the best condition of the weld is discussed.
