Pada penelitian ini, dilakukan penyambungan aluminium AA 6063 menggunakan pengelasan Tungsten Inert Gas (TIG) dengan sambungan tumpul (butt joint). Digunakan metode pengumpanan logam pengisi (filler) secara berselang (intermittent) untuk mencari pengaruhnya terhadap lebar dan tinggi manik, serta kekuatan tarik hasil pengelasan. Dimensi spesimen yang digunakan dalam penelitian ini yaitu panjang 12 mm, lebar 5 mm, dan tebal 3 mm. Pengelasan dilakukan dengan kecepatan dan arus yang tetap, yaitu 1,5 mm/s dan 115 A. Rasio yang digunakan yaitu konfigurasi dari waktu pengumpanan dan waktu diam. Rasio yang divariasikan yaitu rasio 4 hingga 6. Pada masing-masing rasio, terdapat 3 kecepatan filler. Dari hasil penelitian didapatkan, lebar manik berbanding terbalik dengan rasio kecepatan pengumpanan logam pengisi, sedangkan tinggi manik berbanding lurus dengan rasio kecepatan pengumpanan logam pengisi. Dan untuk kekuatan tarik, secara umum nilainya berbanding lurus dengan rasio namun perbedaanya tidak signifikan.
In this research, aluminium 6063 were welded by using Tungsten Inert Gas (TIG) weld on square butt joint. The intermittent filler feed method was proposed to find the corelations between the bead width and tensile strength of weld product. TheĀ dimension of specimen was 12 mm x 5 mm x 3 mm. The welding process was performed with fixed speed of weld and current, 1.5 mm/s and 160 A respectively. The used of ratio is the configuration of the filler time and delay time and was varied from the ratio 4 to ratio 6. In each ratio, there are 3 speed of filler. From the results obtained, the bead width is directly proportional to the ratio of feeding metal filler speed, whereas the bead height is inversely proportional to the ratio of feeding metal filler speed. And for tensile strength, its directly proportional to the ratio however the different is not significant.
"The designed which has been designed in this research, will then be analyzed through analytical calculations and simulations using Autodesk Inventor 2021 software to verify the construction of the TIG welding machine can withstand the load of the designed welding torch. This research will primarily focus on the strength of the TIG welding machine's construction to withstand the load after the welding torch is designed, and then compare the results with the simulation calculations using Inventor software. Analytical load calculations are essential to ensure the safety and strength of the equipment in performing its function. The results of the von mises stress through analytical and simulation before welding torch are 1,49 MPa and 0,24 MPa. Meanwhile the analytical and simulation after welding torch are 0,167 MPa and 0,27 MPa."
