Effect of tool position on microstructural and mechanical properties of friction stir butt welded joint of AA2024–AA7075 dissimilar alloys
In this research, butt joining of Al2024 and Al7075 plates were performed by Friction Stir Welding (FSW) and the effect of tool position on microstructural and mechanical properties in about 1 mm from center line of joint towards the advancing side (AS) and the retreating side (RS) was investigated at three positions of +1, 0, -1 mm. In this regard, the plates of Al2024 and Al7075 were selected...
متن کاملNumerical Crack Growth Analysis in AA2024-T3 Friction Stir Welded Butt Joints
This paper deals with a numerical investigation on the influence of residual stresses on fatigue crack growth in AA2024-T3 friction stir welded butt joints. The computational approach is based on the coupled usage of the finite element method (FEM) and the dual boundary element method (DBEM), in order to take advantage of the main capabilities of the two methods. Linear elastic FE simulations a...
متن کاملInvestigation on Tensile Strength of Friction Stir Welded Joints in PP/EPDM/Clay Nanocomposites
Polymer-based nanocomposites due to their advantages such as corrosion resistance,adequate mechanical properties and low cost are widely used in modern technologies. The increasing application of these nanocomposites, and hence their welding seems unavoidable. In this paper, a novel hottool in friction stir welding process is used for butt welding nanocomposite plates of 5 mm thick containing p...
متن کاملEffect of Tool Speed on Axial Force, Mechanical Properties and Weld Morphology of Friction Stir Welded Joints of A7075-T651
The axial force measurement plays important role in tool designing and identification of its restrictions. Also, it is vital in design of machine mechanism and optimization of welding process parameters. In this study, a friction stir welded butt join on AA7075-T651 aluminum alloy plate is investigated. With change of some parameters, factors including axial force, mechanical properties, microh...
متن کاملAutomatic seam-tracking of friction stir welded T-joints
In this research, a method for implementing automatic seam-tracking for friction stir welding, referred to hear as WeaveTrack, is presented. In this extrumum-seeking control technique, the tool weaves back and forth during welding to maintain the location where axial force is greatest, which is shown to be the center of the weld. Results demonstrate the effectiveness of this technique in tracki...
