Pengelasan merupakan proses penyambungan secara permanen atau lebih material logam dengan ikatan metalurgi yang dihasilkan pada waktu logam dalam keadaan lumer atau cair. AA5052 jenis paduan dengan kekuatan tertinggi dari kelas yang lebih tidak dapat diolah panas. Kekuatan kelelahannya lebih tinggi dari kebanyakan kelas aluminium lainnya. Alloy 5052 memiliki ketahanan yang baik terhadap atmosfer laut dan korosi air asin, serta kemampuan kerja yang sangat baik. Itu dapat dengan mudah di gambar atau dibentuk menjadi bentuk yang rumit. Finite Element Analysis (FEA) jenis perangkat lunak yang memudahkan untuk menganalisa simulasi diantaranya solid mechanics, thermal analysis, heat transfer, fluid mechanics, electromagnetics. Tujuan dari penelitian ini untuk mengetahui beban dan pengaruh tegangan pada variasi kampuh dengan pengujian static di solidworks, serta untuk mengetahui pengaruh beban dan tegangan terhadap faktor keamanan pada variasi sudut kampuh menggunakan solidworks. Metode yang digunakan melalui pendekatan 3D, membuat mesh, membuat simulasi beban static. Hasil analisa tegangan maksimum untuk sudut 60o sebesar 33.146 Mpa, sudut 70o sebesar 33.059 Mpa, sudut 800 sebesar 33.006 Mpa, sudut 90o sebesar 33.078 Mpa dan tegangan minimum sudut 60o sebesar 0.571 Mpa, sudut 70o sebesar 0.193 Mpa, sudut 80o sebesar 0.559 Mpa, sudut 90o sebesar 0.518 Mpa. Perubahan (displacement) maksimum sehingga terjadi deformasi plastis ditunjukkan dengan warna merah 0.010 mm dan perubahan minimum ditunjukkan dengan warna biru 0,001 mm. Dari analisis yang dilakukan, perubahan yang diijinkan ketika dikenai beban yaitu dengan jarak displacement 0,07 mm. Hasil analisa ini diharapkan dapat menjadi masukan yang baik untuk struktur yang sudah dibuat maupun yang akan dikembangkan baik dalam proses keselamatan maupun pemilihan material.

“…Finite element simulations are generally very often used in literature to simulate the FSW process, e.g. [10][11][12][13], with a comprehensive review given in [14]. However, there are some interesting recent studies showing the application of other mathematical tools, such as cellular automaton model [2], or wavelet analysis [15] in modelling of this welding technique.…”

The influence of friction stir welding (FSW) parameters on thermo-mechanical behaviour of the material during welding is analysed. An aluminium alloy is considered (Al 2024 T351), and different rotating speed and welding speed are applied. Finite element model consists of the plate (Al alloy), backing plate and welding tool, and it is formed and solved in software package Simulia Abaqus. The influence of the welding conditions on material behaviour is taken into account by application of the Johnson-Cook material model. The rotation of the tool affects the results: if increased, it contributes to an increase of friction-generated heat intensity. The other component of the generated heat, the plastic deformation of the material, is negligibly changed. When the welding speed is increased, the intensity of friction-generated heat decreases, while the heat generation due to plastic deforming increases. Combined, these two effects cause small change of the total heat generation. For the same welded joint length, the plate welded by lower speed will be heated more intensively. The changes of the heat generation influence both the temperature field and reaction force, which are also considered.

“…A wide area forms in the region that narrows towards the edge of the metal in this softened thermal area but displays friction with shoulder part of the tool (Fig. 1) [19][20][21][22][23]. This technique has made it easy to join many products for which it is very difficult to perform a good weld without any gap, crack or a distortion in the part with welding.…”

The effecTs of fricTion sTir Welding ParameTers on microsTrucTure, faTigue life and Tensile ProPerTies of aluminum 2024-T3 alloy ın this study, Al 2024-T3 alloy plates were joined by using friction stir welding. Welding was performed at a rotational speed of 930, 1450, 2280 rpm and a welding feed rate of 180 mm min −1 . The welded samples were analyzed at the microstructural level. Moreover, both bending fatigue tests and tensile tests were performed on samples. At the end of the microstructural examination of the samples welded at the rotational speed of 930 rpm and the welding feed rate of 180 mm min −1 , the formation of tunnel defects was observed. The highest fatigue life was obtained at 2280 rpm and 180 mm min −1 . The lowest fatigue life was obtained at 930 rpm and 180 mm min −1 . The highest ultimate tensile stress was obtained at 2280 rpm/180 mm min -1 sample, which shows about a 12% reduction relative to the base material. The lowest ultimate tensile stress was obtained at 930 rpm/180 mm min -1 sample. The ultimate tensile stress value of the 930 rpm/180 mm min -1 sample decreased by approximately 25%.
