Analysis and Comparison of Friction Stir Welding and Laser Assisted Friction Stir Welding of Aluminum Alloy
Friction Stir Welding (FSW) is a solid-state joining process; i.e., no melting occurs. The welding process is promoted by the rotation and translation of an axis-symmetric non-consumable tool along the weld centerline. Thus, the FSW process is performed at much lower temperatures than conventional fusion welding, nevertheless it has some disadvantages. Laser Assisted Friction Stir Welding (LAFS...
متن کاملEffects of Process Parameters of Friction Stir Processing on Tensile Strength of AA6063 Aluminum Alloy
In this investigation, the effect of friction stir processing (FSP) parameters such as rotational speed, traverse speed and plunge depth on the tensile strength of AA6063 aluminum alloy was studied. The experiments were carried out as per response surface methodology parametric design concepts to study the influence of various combinations of process parameters.

متن کاملUltra-Fine Grained Dual-Phase Steels
This paper provides an overview on obtaining low-carbon ultra-fine grained dual-phase steels through rapid intercritical annealing of cold-rolled sheet as improved materials for automotive applications. A laboratory processing route was designed that involves cold-rolling of a tempered martensite structure followed by a second tempering step to produce a fine grained aggregate of ferrite and ca...
متن کاملStudying the Possibility to Weld AA1100 Aluminum Alloy by Friction Stir Spot Welding
Abstract—Friction stir welding is a modern and an environmentally friendly solid state joining process used to joint relatively lighter family of materials. Recently, friction stir spot welding has been used instead of resistance spot welding which has received considerable attention from the automotive industry. It is environmentally friendly process that eliminated heat and pollution. In this...
متن کاملEvaluation of fatigue behavior of cast and ultra-fine processed Al-7075 by using friction stir technique
This paper presents experimental results on the fatigue properties of the modified microstructure of cost Al-alloy 7075 via friction stir processing (FSP). The microstructural behavior was investigated by using optical microscope (OM). The grain size of cast FSP-ed at different locations was investigated via XRD. Uniaxial tensile and bending fatigue tests were carried out at room temperature o...
