Welding dissimilar materials has been widely applied in industries. Some of them are considered this as a strategy to develop their future technology products. Aluminum alloy and stainless steel have differences in physical, thermal, mechanical and metallurgic properties. However, selecting a suitable welding process and welding rods can solve this problem. This research aimed to investigate the T-joint welding between A6061 aluminum alloy and SUS304 stainless steel using new welding rods, Aluma-Steel by the Tungsten Inert Gas (TIG) welding process. The mechanical properties, the characteristics of microstructure, and component analysis of the welds have been investigated by the mechanical testing, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). As a result, the fracture occurred at the adjacent area between welding seam and A6061 alloys plate. The thermal cracking appeared at central welding-seam along the base metals if high welding current. A large amount of copper elements found in the welds due to using the new welding rod, Aluma-Steel rod.

Tujuan dari penelitian ini untuk mengetahui kekuatan tarik stainless steel 304 dari pengelasan GTAW dengan variasi kuat arus dan debit aliran gas. Metode penelitian yang digunakan adalah penelitian eksperimental dengan variasi kuat arus 80A, 90A dan 100A dan debit aliran gas pelindung sebesar 8 L/menit dan 10 L/menit. Sampel untuk pengujian menggunakan standar uji ASTM E8/E8M-09. Hasil analisis statistik kuat arus menunjukkan  bahwa nilai signifikansi sebesar 0.032 lebih kecil dari 0,05, atau H0 ditolak artinya  penggunaan variasi kuat arus berpengaruh terhadap kekuatan tarik. Sedangkan analisis statistik untuk dabit aliran gas palindung menunjukkan  bahwa nilai signifikansi sebesar 0.144 lebih besar dari 0,05, atau H0 tidak ditolak artinya penggunaan variasi debit aliran gas pelindung tidak berpengaruh terhadap kekuatan tarik. Nilai kekuatan tarik tertinggi terdapat pada penggunaan arus 90A dengan debit aliran gas 8 L/menit sebesar 610,54 Mpa. Nilai kekuatan tarik terendah terdapat pada penggunaan arus 80A dengan debit aliran gas10 L/menit sebesar 560,89 Mpa.Kata Kunci: Stainless Steel, GTAW, Kua Tarik, Tungsten Inert Gas
