Analisis Hasil Double Side Friction Stir Welding pada Aluminium AA6061 dengan Penguat Serbuk Cu terhadap Struktur Mikro

نویسندگان

چکیده

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). Material digunakan aluminium kode AA6061 (Cu) dipilih sebagai bahan utama. Penambahan Cu diletak kan (single grove) (double grove). Proses DS-FSW menggunakan CnC milling parameter feed rate 80 mm/menit kecepatan putaran tools 1000 rpm. Pengamatan USB Digital Mikroskop, sedangkan pengamatan struktur Metallography optic. Hasil menunjukkan bahwa single grove double sama –sama mengalami cacat diantaranya tunnel defect, namun defect memiliki dimensi lebih besar grove. observasi distribusi overlap terletak para grove, hal tersebut terjadi karena letak pin berada simetris antara dua sudah terisi Cu, sehingga pengadukannya bisa merata.

Friction 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...

Review: 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...

Experimental investigation of Tool Geometry on Mechanical Properties of Friction Stir Welding of AA6061

AA 6061 has gathered wide acceptance in the fabrication of the light structures required to high strength. Compared to the fusion welding processes that are used for joining structural aluminium alloys, friction stir welding (FSW) process is an emerging solid state joining process in which the material that is being welded does not melt and recast. In this experimental work, an extensive invest...

Analysis and Comparison of Friction Stir Welding and Laser Assisted Friction Stir Welding of Aluminum Alloy

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...
