“…The highest tensile test score was 163.7 MPa by C-B 45 joint on 10 mm/min feedrate speed. The temperature distribution reached 420°C, consequently forming plastic state on the work-piece [14]. This study aims to evaluate a new design of fitting model single U and double U for FSW in Aluminum welding.…”

Parallel, lap, corner, and T joints are commonly used in fusion welding and solid welding. Other joints made are lap and butt joint. This study aims to evaluate a new design of fitting model single U and double U for friction stirr welding of Aluminum. Aluminum sheet 6061with a thickness of 10 mm, will be cut to a length of 150 mm and a width of 100 mm, then a locking groove will be made with an inner size of 5 mm and a length of 150 mm The flow is used to be paired in the FSW process. This experiment results show the high tensile strength that occurs in the double joint u, is 13.4 kN while the average is 12 kN. Single connection experiment u the highest tensile strength is 12.89 kN, while the average value is 10.37 kN. The hardness is higher in double u joints compared to single u joints.

Friction stir welding (FSW) adalah salah satu jenis pengelasan yang mampu menyambung bahan paduan aluminium. Pada penelitian sebelumnya telah dilakukan penyambungan aluminium 5052 namun hasil pengujian tarik memperlihatkan penurunan kekuatan sambungan. Sehingga pada studi ini bertujuan untuk mengevaluasi secara focus mikrostuktur yang terbentuk pada sambungan plat aluminium 5052 yang telah dilakukan FSW. Plat aluminium dengan dimensi 150 x 75 mm dengan tebal 6 mm dilas dengan metode FSW, pahat pin berbentuk silinder pada kecepatan putar 1000 rpm dan laju pengelasan 20, 30 dan 40 mm/menit. Penampang hasil las diamati dengan menggunakan mikroskop optic dan Scanning Electron Microscope (SEM). Hasil pengamatan memperlihatkan adanya cacat makro dan perubahan struktur mikro pada sambungan. Cacat ini dipengaruhi desain pin yang tidak tepat sehingga daerah adukan tidak merata yang berakibat sambungan menjadi tidak sempurna.Friction stir welding (FSW) is one type of welding that is able to joining aluminium alloy. In previous studies, aluminium 5052 has been joined, but the results of the tensile test showed a decrease in the strength of the connection. Therefore, in this study the aim is to focus on evaluating the microstructure formed at the 5052 aluminium plate welding join that has been carried out by FSW. Aluminium plates with dimensions of 150 x 75 mm with a thickness of 6 mm were welded by the FSW method, cylindrical pin chisel at a rotational speed of 1000 rpm and welding rates of 20, 30 and 40 mm/minute. The cross section of the weld was observed using an optical microscope and Scanning Electron Microscope (SEM). The results of the observations showed that there were macro defects and changes in the microstructure of the joints. This defect is influenced by the improper design of the pin so that the area of the mixture is uneven which results in an imperfect connection
