| Abstract | ||
| This study is concerned with the effect of fiction stir welding parameters on the mechanical properties and the consumed welding power for AA2024-T35 joints. AA2024-T35 was friction stir welded at different welding speeds (16, 40 and 80 mmlmin), rotation speed (900, 1120 and 1400 rpm) and two tool pmfiles (triangular and square). The welding power was measured and evaluated with two previously established models [1,2]. The tool profile as well as the welding speed showed significant effect on the microstructure especially at lower welding speeds. The increase of the welding speed improves the mechanical properties for both tool profiles whereas it has an insignificant effect on the welding power. The square profile produced better mechanical properties and consumed more power, at 40 mmlmin, than the triangular one. Also, the welding speed showed a weak effect on the welding power, hut the need of power increased with the increase of the rotation speed. The measured power was found to he in agreement with the computed one through a theoretical work established by Heurtier et al. | ||
