“…The results indicated that the friction-stir-welding tool geometry considerably influences the material flow in the nugget zone and, consequently, the weld mechanical properties. 26 The influence of the pin geometry on various properties of friction-stir-welded samples made with tools with different pin profiles was proved. In the case of four-flute cylindrical-pin profiles, friction-stir welding could not be performed on an aluminium alloy.…”

Friction-stir welding (FSW) is an unyielding-state welding process developed by The Welding Institute, United Kingdom. FSW is mainly based on the tool geometry, process parameters and welding material. The tool geometry plays the principle role in obtaining desirable microstructures of the welds, improving the strength and fatigue resistance of the joints. Currently, friction-stir-welding tools are designed using the trial-and-error method. In this study, three different types of FSW tools are considered for the fabrication of butt joints from AA5383 and AA7075. Various tool profiles such as the cylindrical taper projection, cylindrical thread-pin projection and triangle-pin projection are considered in the present study. The pin profiles are assessed based on the weld quality during tensile tests and hardness tests conducted on welded samples. With the analysis, it is found that the triangular pin produces sound welds at an 800-min-1 speed, 20-mm/min feed and 4-kN load.

“…The FSW process is used to weld a 6.3 mm thickness of AA6063 -T1 aluminum alloy butt joint. The mechanical properties such as a tensile strength and a hardness of the joint were examined and compared with the microstructure of the joint [6]. The optimum welding condition for the friction stir welding (FSW) process applied to AHSS was considered.…”

Two sheets of aluminium 6061-T6 alloy of size 400×150×3 (mm) is butt welded by the friction stir welding by varying the process parameter such as rotational speed, tilt angle and feed. The ranges of process parameters are rotational speed 560, 900 and 1400 RPM, tilt angle 0, 0.5 and 1 and feed 20, 63 and 100 mm/min. The hexagonal shape of probe is taken to carry out the friction stir welding. The Taguchi L9 experimental approach is used to draw the 9 experimental conditions. The temperature at the weld bead as well as on the probe during the welding is measured by the help of a LASER gun. The hardness at the weld bead and parent metal is measured after the welding. Taguchi L9 approach is used to optimize the process parameters to identify the individual as well as simultaneous effects of the process parameters on the responses temperature and hardness of the weld joint. The optimum conditions for the better fitment of the process parameter and responses are identified through this experimentation.
