Three-dimensional nonlinear thermal and thermo-mechanical numerical simulations are conducted for the friction stir welding (FSW) of 304L stainless steel. The finite element analysis code—WELDSIM, developed by the authors specifically for welding simulation, was used. Two welding cases with tool rotational speeds of 300 and 500 rpm are analyzed. The objective is to study the variation of transi...

Over the last decade attempts have been made to fabricate aluminum matrix composites (AMCs) reinforced with several ceramic particles. Aluminum reinforced with ZrB2 particles is one such AMC. The successful application of new kind of AMCs lies in the development of secondary processes such as machining and joining. Friction stir welding (FSW) is a relatively new solid state welding which overco...

The welding of materials by applying Friction Stir Welding technique is a new solid-state joining technique. The main advantage of this method compared to the traditional joining process is that it minimizes problem-related to metal resolidification as the method incorporates no melting phase. In this experimental work, the effect of friction stir welding (FSW) technique on the microstructu...

The general principles behind the global mechanical tensioning technique for controlling weld residual stresses are examined using a finite lement model to follow their evolution throughout the welding process. While we focus specifically on friction stir welding, the tool is represented imply as a heat source. As a result, the findings have relevance to a wide range of welding processes. For a...

Friction Stir Welding is a suitable solid-state joining technology to connect dissimilar materials. To produce an effective joint, phase of optimization required which leads the definition process parameters such as pin geometry, tool rotational speed, rotation direction, welding thickness sheets or tilt angle. The aim this review present complete and detailed frame main their effect on final p...

For hot extrusions of magnesium alloy sheets, Dissimilar AZ80 and AZ31 were used, in which AZ80 was placed on advancing side and AZ31 on retreating side, using friction stir butt welding with different process parameters. Some defect-free welded joints with good weld surfaces could be obtained with some suitable welding conditions. The maximum tensile strength of welded joint which is 225.5 MPa...
