EFFECTS OF TOOL-WORKPIECE INTERFACE TEMPERATURE ON WELD QUALITY AND QUALITY IMPROVEMENTS THROUGH TEMPERATURE CONTROL IN FRICTION STIR WELDING Axel Fehren...
This paper analyzes local lattice rotations introduced in severely deformed polycrystalline titanium by friction stir welding. Nondestructive three-dimensional (3D) spatially resolved polychromatic X-ray microdiffraction, is used to resolve the local crystal structure of the restructured surface from neighboring local structures in the sample material. The measurements reveal strong gradients o...
friction welding is widely used in various industries. in friction welding, heat is generated by conversion of mechanical energy into thermal energy at the interface the work pieces during pin rotation under pressure. a three-dimensional thermo mechanical simulation of friction stir welding (fsw) processes is carried out for aluminium alloys of 6061and 7050 where the simulation results are comp...
Solid state joining of powder metallurgy (P/M) processed and sintered by spark plasma sintering through friction stir welding (FSW) was studied. The nanocomposites were prepared via mechanical milling followed by spark plasma sintering. The microstructural and mechanical of the joints were evaluated as a function of the different processing parameters such as rotating and advancing speeds of th...
In this study, the effect of toolchr('39')s advance velocity on the mechanical behavior of the Al-7075 alloy during friction stir welding was simulated. In this simulation, the Lagrangian method with rigid-Visco-plastic material was used. The results of the process temperature obtained by the simulation method were verified by the experimental welding test. Using the characteristic stress, stra...
