A novel approach for predicting the intermetallic compound (IMC) formation during friction stir welding (FSW) of AA6061 to commercially pure copper has been developed, in addition their effect on mechanical properties. The temperature distribution aluminium weld nugget determined by a finite element model, use an Al–Cu phase diagram and elemental concentration have combined predict validate sev...
Electrical-current-assisted friction stir welding (EA-FSW) is a procedure developed for the joining of similar and dissimilar materials. EA-FSW newly invented solid-state process to increase welded components’ efficacy in various applications, such as marine structures. joints have investigated on aluminum–magnesium, aluminum–steel, polymer-to-steel. Similar been performed aluminum, magnesium, ...
Purpose – The weld joint of large thin-wall metal parts which deforms in manufacturing and clamping processes is very difficult to manufacture for its shape is different from the initial model; thus, the space normals of the part surface are uncertain. Design/methodology/approach – In this paper, an effective method is presented to calculate cutter location points and to estimate the space norm...
Abstract Friction stir welding is a solid state joining method used to join materials which cannot be joined by fusion welding. In this method, heat produced due the friction between tool and workpiece weld material. Heat input depends upon amount of caused process parameters such as rotational speed, geometry, axial force etc. present study, effect shoulder pin diameter ratio, speed on peak te...
Welding parameters for pipe joint friction stir welding (FSW) have been identified based on L-9 orthogonal arrays used in the Taguchi Method. Different parameters, such as rotation speed, travel speed and axial force, to produce several quality welded AA6063 butt joints. The reliability of products obtained FSW process can be improved through identification optimum combination parameters. Weld ...
In this study, thermo-mechanical stability of two-pass constrained groove pressing (CGP) AA1050 sheets towards friction stir welding (FSW) employing hybrid powder (%50vol. micrometric graphite powder+%50vol. α-Al2O3 nanoparticles) was investigated by examining its microstructural evolutions and mechanical properties. FSW was carried out via different process variables in order to reach the high...
Friction stir welding (FSW) is an economic and high quality technique at aluminum welding and joining methods. The most important factor in the soundness of this type of welding, is the mechanism of material transfer in each tool rotation. The materials transfer during the welding process involves horizontal and vertical movement that caused by extrusion process and forging force (the tilt angl...
Effect of Heat Input on Microstructure and Mechanical Properties in Friction Stir Welding of HSLA-60
High-strength low alloy steels are a class of steels used in applications that require high strength and good weldability, including ship hulls, gas pipelines and oil industry. One way to build parts is fusion welding that create areas with a large grain size in the heat-affected zone and increased susceptibility to hydrogen cracking. One way to solve this problem is to use solid state friction...
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...
