Micro friction stir welding (μFSW) adalah pengelasan untuk ketebalan maksimal 1 mm. Tujuan penelitian mengetahui pengaruh feed rate dan sudut kemiringan pin tool pada μFSW aluminium 1100. Pengelasan dilakukan dengan variasi 0°,1° 2°, 66, 85, 120 mm/menit serta kecepatan putaran 2280 rpm. Jenis sambungan yang digunakan butt. Pengujian pengujian struktur mikro cacat makro mikroskop optik, uji kekerasan, kekuatan tarik. Hasil pengamatan terdapat lasan yaitu incomplete fussion. menunjukkan bahwa grain size zone (SZ) semua tampak lebih kecil dibandingkan BM HAZ menyebabkan nilai kekerasan SZ tinggi dari BM. Semakin bertambah maka daerah tarik semakin meningkat. Heat input mengakibatkan pendinginan lambat sehingga butiran besar penurunan kekerasan. Kekerasan tertinggi sebesar 73,7 VHN 2o 64,7 VHN.

Optimization of Friction Stir Welding Tool Advance Speed via Monte-Carlo Simulation of the Friction Stir Welding Process
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...
متن کاملFriction stir welding and processing
Friction stir welding (FSW) is a relatively new solid-state joining process. This joining technique is energy efficient, environment friendly, and versatile. In particular, it can be used to join high-strength aerospace aluminum alloys and other metallic alloys that are hard to weld by conventional fusion welding. FSW is considered to be the most significant development in metal joining in a de...
متن کاملReview: friction stir welding tools
Friction stir welding (FSW) is a widely used solid state joining process for soft materials such as aluminium alloys because it avoids many of the common problems of fusion welding. Commercial feasibility of the FSW process for harder alloys such as steels and titanium alloys awaits the development of cost effective and durable tools which lead to structurally sound welds consistently. Material...
متن کاملTool Geometry for Friction Stir Welding—Optimum Shoulder Diameter
The most important geometric parameter in the friction stir welding (FSW) tool design is the shoulder diameter, which is currently estimated by trial and error. Here, we report a combined experimental and theoretical investigation on the influence of shoulder diameter on thermal cycles, peak temperatures, power requirements, and torque during FSW of AA7075-T6. An optimum tool shoulder diameter ...
متن کاملDesign of Friction Stir Welding Tool for Avoiding Root Flaws
In order to improve material flow behavior during friction stir welding and avoid root flaws of weld, a tool with a half-screw pin and a tool with a tapered-flute pin are suggested. The effect of flute geometry in tool pins on material flow velocity is investigated by the software ANSYS FLUENT. Numerical simulation results show that high material flow velocity appears near the rotational tool a...
