Abstract

AbstractIn the process of finding the principal dimension of the ship there are various methods that can be used. In this study, the Comparison method will be used to obtain the main size of the ship and the main dimensions of the ship are obtained, namely, length (L) = 20,152 meters, beam (B) = 5.5 meters, depth (H) = 2,939 meters, draft (T) = 1.5129 meters, service speed (Vs) = 20 knots. The ship's resistance is 152.6 kN at service speed (Vs) = 20 knots. And can be overcome with a power of 2426.31 HP. The power taken to meet these needs is 2500 HP supplied by 2 outboard engines with a power of 1300 HP each.Keywords : Comparison Method.

Abstract

Penelitian ini bertujuan untuk menganalisa pengaruh root gap terhadap pengujian tarik (Tensile Test) pada material baja SS 400 dengan ketebalan 10 mm dan 12 mm menggunakan metode pengelasan FCAW (Flux Core Arc Welding) pada posisi 3G Vertical up tanpa backing ceramic. Penelitian ini bersifat kuantitatif, kemudian standar yang digunakan dalam pengujian yaitu ASME section IX (2019). Hasil penelitian diperoleh kesimpulan pada spesimen dengan ketebalan 10 mm, didapatkan nilai tertinggi pada variasi root gap 2 mm dengan nilai YS (Yield Strenght) sebesar : 242,07 MPa, dan nilai aktual / nilai akhir sebesar : 315,33 MPa. Kemudian pada spesimen dengan ketebalan 12 mm, didapatkan nilai tertinggi terdapat pada variasi 3 mm dengan nilai YS (Yield Strenght) sebesar: 296,57 MPa, dan nilai aktual / nilai akhir sebesar: 464,17 MPa.

Abstract

This study aims to analyze the effect of the root gap on bending test of SS 400 steel materials with different thicknesses of 10 mm and 12 mm using FCAW (Flux Core Arc Welding) welding in the 3G Vertical up position without backing ceramic. This study uses quantitative method, and the standard used in the test is ASME section IX (2019). The results of the study concluded that in specimens within the thickness of 10 mm, the highest value was obtained at the root gap variation of 4.4 mm with a bending stress value of: 467.48 MPa. Then on the specimen with a thickness of 12 mm, the highest value was found in a variation of 3 mm with a bending stress value of: 805.37 MPa
