The Mechanical Properties Evaluation of the Welded Sheets of AA 3105 Aluminum Alloy Using Friction Stir Spot Welding (FSSW)
Friction stir spot welding (FSSW) is a type of solid state welding that is used in the connection of small pieces and light metals such as aluminum alloy especially. The technical problem during melting of aluminum alloys is one of the most important reasons for developing application of friction stir welding for aluminum alloys. In this research, the effects of important processing parameters ...

متن کاملEffects of Rotational Velocity on Microstructures and Mechanical Properties of Surface Compensation Friction Stir Welded 6005a- T6 Aluminum Alloy
Article history: Received: 4.7.2014. Received in revised form: 2.9.2014. Accepted: 3.9.2014. Surface compensation friction stir welding (SCFSW) is successfully applied to weld 6005A-T6 aluminum alloy in order to eliminate disadvantages caused by flash and arc corrugation. The effects of rotational velocity on the microstructures and mechanical properties of SCFSW joints are investigated. The jo...
متن کاملA Coupled Rigid-viscoplastic Numerical Modeling for Evaluating Effects of Shoulder Geometry on Friction Stir-welded Aluminum Alloys
Shoulder geometry of tool plays an important role in friction-stir welding because it controls thermal interactions and heat generation. This work is proposed and developed a coupled rigid-viscoplastic numerical modeling based on computational fluid dynamics and finite element calculations aiming to understand these interactions. Model solves mass conservation, momentum, and energy equations in...
متن کاملevaluation of fatigue life of friction stir welded 7075-t651 aluminum alloy joints
abstract – aluminium 7075- t651 alloys are widely used in the production of light weight structures requiring a high strength to weight ratio and high corrosion resistance. the effect of processing parameters on fatigue life of 7075- t651 aluminium joints produced by friction stir welding was investigated in the present study. welding samples were made by employing rotating tool speed of 770, 9...
