Abstract

Industri maritim menggunakan material logam yang kuat karenanya diperlukan dalam aplikasi struktur lepas pantai. Salah satu contoh materialnya adalah baja ASTM A36. Baja ASTM A36 banyak digunakan dalam struktur lepas pantai karena kekuatan dan ketahannya terhadap beban, namun sifat material logam ini rentan terkena kelelahan atau fatigue akibat dari lingkungan di lepas pantai. Penelitian ini bertujuan untuk menganalisis variasi heat input dan groove angle pada kekuatan tarik dan struktur metalografi dari material baja ASTM A36. Pengujian ini akan dilakukan dengan variasi masukan panas batasan arus listrik rendah (90A), sedang (120A), dan tinggi (160A) dikombinasikan dengan variasi sudut umum (60°), lebar (75°), dan eksperimental (90°) pada kampuh pengelasan. Dengan variasi tersebut, akan dilakukan uji kekuatan tarik dan uji struktur metalografi. Hasil penelitian ini dapat memberi pemahaman lebih mendalam tentang optimalisasi teknik pengelasan pada struktur baja di lingkungan maritim, sehingga dapat meningkatkan efisiensi dalam aplikasi struktur lepas pantai baik dunia akademisi institusi maupun hasil observasi lapangan.

The maritime industry uses strong metallic materials hence required in offshore structural applications. One example of the material is ASTM A36 steel. ASTM A36 steel is widely used in offshore structures due to its strength and resistance to loads, but the nature of this metal material is susceptible to fatigue due to the offshore environment. This research aims to analyze the variation of heat input and groove angle on the tensile strength and metallographic structure of ASTM A36 steel material. This test will be conducted with heat input variations of low (90A), medium (120A), and high (160A) electric current limitation combined with generic (60°), wide (75°), and experimental (90°) angle variations on the welding seam. Upon these variations, tensile strength tests and metallographic structure tests will be carried out. The results of this research are to provide a deeper understanding of the optimization of welding techniques on steel structures in the maritime environment, so as to increase efficiency in the application of offshore structures both in the world of academic institutions and field observations.
