Optimization of Process Parameters of Friction Stirs Welding of Aluminum Alloys (6061) Using Taguchi Method
Friction Stir Welding (FSW) is considered to be the most significant development in metal joining technologies to join high strength aerospace aluminum alloys. In order to improve the reliability and quality of the products manufactured by FSW process input process parameters such as tool rotational speed, welding speed and axial force are to be optimized. This study deals with the optimization...
متن کاملLiquation Cracking of Dissimilar Aluminum Alloys during Friction Stir Welding
A liquation cracking mechanism of dissimilar Al alloys during the friction stir welding (FSW) is suggested in this study. To identify the mechanism, the precipitates were analyzed and Al-Mg-Cu phase diagrams were calculated. Electron backscattering diffraction (EBSD) analysis and electron probe microanalysis (EPMA) were also conducted. In the same manner as constitutional liquation, at high hea...
متن کاملMetallurgical and Mechanical Behavior of AISI 316- AISI 304 during Friction Welding Process
Present study focuses on the micro-structural and mechanical behavior effect of friction time for similar (AISI 316-AISI 316 and AISI 304-AISI 304) and dissimilar (AISI 304-AISI 316) joint during continuous drive friction welding. The welding carried out with different friction time: 6.5, 8.5 and 10 s while kept all other conditions constant. The effect of that time on the strength, structural ...
متن کاملFriction Stir Welding of Aluminum Alloys: A Review
Friction stir welding is a solid state joining process. High strength aluminum alloys are widely used in aircraft and marine industries. Generally, the mechanical properties of fusion welded aluminum joints are poor. As friction stir welding occurs in solid state, no solidification structures are created thereby eliminating the brittle and eutectic phases common in fusion welding of high streng...
متن کاملCoupled Eulerian-Lagrangian (CEL) Modeling of Material Flow in Dissimilar Friction Stir Welding of Aluminum Alloys
In this work, the finite element simulation of dissimilar friction stir welding process is investigated. The welded materials are AA 6061-T6 and AA 7075-T6 aluminum alloys. For this purpose, a 3D coupled thermo-mechanical finite element model is developed according to the Coupled Eulerian-Lagrangian (CEL) method. The CEL method has the advantages of both Lagrangian and Eulerian approaches, whic...
