This present study aimed to create an Al6061-St52 dissimilar joint and investigate the effect of the transverse speed by the friction stir welding process. Welding aluminum to steel is rugged by fusion methods because of the formation of brittle intermetallic compounds (IMCs). Therefore, to designate optimal parameters, acceptable IMC thickness, and mechanical properties determined. This resear...
Recognition of the friction stir welding process is growing in the aeronautical and aero-space industries. To make the process more available to the structural fabrication industry (buildings and bridges), being able to model the process to determine the highest speed of advance possible that will not cause unwanted welding defects is desirable. A numerical solution to the transient two-dimensi...
Background: AA2519-T87 is a new armour grade aluminium alloy employed in the fabrication of light combat military vehicles. Joining of this material using fusion welding processes, results in the formation of solidification defects like porosity, alloy segregation and hot cracking. In order to overcome the solidification related problems, solid state welding processes such as friction stir weld...
In this study, the effects of linear speed and rotational speed of the friction stir welding tool was investigated on the heat generation and distribution of heat,the material flow and weld defect formation of the Polyamide 6 (PA6) workpiece. The commercial CFD Fluent 6.4 software package was used to the simulation of the process with computational fluid dynamic technique. The output results of...
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...
It is important to join materials for systems that require high-performance and minimize the defects may occur during this joining. Welding most common way joining but lightweight similar/ dissimilar materials, Friction Stir preferable its properties. Lightweight durable such as aluminum alloys are widely used in sectors defense industry, aerospace automotive high-speed train manufacturing. Som...
