Abstract
In this work, friction stir welding with self-reacting tool is presented. Materials used for friction stir welding tools are presented, as well as the geometry and tool kinematics. A special attention is paid to self-reacting tools, two sided tools that also act as base plate and weld the base material by forming both the face and the root of the weld. Experimental work was done on six specimens, with two tool geometries, three different rotational speeds and a single welding speed, on technical aluminium. The results shown that a higher weld quality was obtained by applying the tool with a higher shoulder angle and a higher rotational speed.
