Pengelasan Friction Stir Welding (FSW) adalah metode pengelasan sederhana, yaitu dengan memanfaatkan energi panas yang ditimbulkan dari gesekan shoulder tool material dilas. FSW sedang berkembang saat ini menambahkan serbuk pada daerah nugget untuk meningkatkan kemampuan las. Pada penelitian bertujuan mengetahui hasil secara foto makro dan mikro overlapping Double Side (DS-FSW) tembaga (Cu). Ma...

Friction stir welding (FSW) is a solid state welding process, which is used for the welding of aluminum alloys. It is important to note that the mechanical properties of the FSW process depends on various process parameters, such as spindle speed, feed rate and shoulder depth. Two different tool materials, such as High speed steel (HSS) and H13 are considered for the welding of Al 7075. The pre...

In this paper, the friction stir welding (FSW) of single curvature and double “S” curved surface lap joints were realized using split-type pressing blocks fixture robotic system with parameter 1400 rpm, 150 mm/min. By finite element method (FEM) axial force analysis, effects direction on joint 5083 aluminum alloy is explored. The results show that Z-axis has important influence forming. positiv...

Friction stir welding is gaining significance in typical joining applications day by day. Modeling and simulation of FSW has been a great challenge due to the complexity of the process. We are initiating an effort to review various modeling and simulation techniques mentioned in literature and to find the future scope and possibilities of new techniques.

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, ...

In this work, a finite-element model was elaborated to simulate the thermomechanical behavior of 6061 aluminum alloy during friction-stir welding (FSW). It shown that FSW-induced deformation is two-stage process. addition stirring action exerted by rotating tool probe, material in near-surface area stir zone also experienced secondary shoulder edge after passage tool. Both steps were found be c...

constant communication with an intelligence analyst at operations command, and receives orders through an earpiece to don chemical-protection equipment because of new chemical weapons threat intelligence in the area. The chemical-protection suit is similar to but weighs less than those in use today. Most importantly, because it encloses the soldier's head, the suit has an augmented hearing syst...
