Effect of Heat Input on Tensile Properties of Friction Stir Welded AA6061-T6 and AA7075-T6 Dissimilar Aluminum Alloy Joints
Friction Stir Welding (FSW) is a solid state process widely used to join dissimilar aluminium alloys. High quality and strength joints can be fabricated using this technique when compared to other conventional methods. The welding parameters play major role in determining the quality of the weld. This paper aims in presenting the effect of heat input on tensile properties of the joints between ...
متن کاملMicrostructure and Tensile Behavior of Laser Arc Hybrid Welded Dissimilar Al and Ti Alloys
Fiber laser-cold metal transfer arc hybrid welding was developed to welding-braze dissimilar Al and Ti alloys in butt configuration. Microstructure, interface properties, tensile behavior, and their relationships were investigated in detail. The results show the cross-weld tensile strength of the joints is up to 213 MPa, 95.5% of same Al weld. The optimal range of heat input for accepted joints...
متن کاملAn Assessment of the Mechanical Properties and Microstructural Analysis of Dissimilar Material Welded Joint between Alloy 617 and 12Cr Steel
The most effective method to reduce CO2 gas emission from the steam power plant is to improve its performance by elevating the steam temperature to more than 700 ◦C. For this, it is necessary to develop applicable materials at high temperatures. Ni-based Alloy 617 and 12Cr steel are used in steam power plants, due to their remarkable mechanical properties, high corrosion resistance, and creep s...
متن کاملRelation between Residual Stress and Fatigue Strength for Electron Beam Welded Joints of Sheet Metal
Residual stresses in welds significantly affect the fatigue strength and stress corrosion crack resistance of the weld joint, and therefore, numerous studies have been made about the effects. The residual stress induced by electron beam welding (EBW) has also been researched in various approaches, but many of the study reports dealt with thick plates (50 mm or thicker) only.1–5) This was becaus...
متن کاملEvaluation of microstructure and mechanical properties of friction stir welded copper / 316L stainless steel dissimilar metals
In the present research, friction stir welding (FSW) process was used for butt joining of pure copper plate to 316L stainless steel plate. Mechanical properties and microstructural characteristics of the joint were evaluated by microhardness and tensile tests as well as optical and scanning electron microscope (SEM). It was found that microstructure of the weld nugget (WN) has fine grains where...
