The International Journal of Mechanics, Energy Engineering and Applied Science (IJMEAS) is a double-blind peer-reviewed journal. This journal provides full open access to its content on the principle that making research freely and independently available to the science community and the public supports a greater global exchange of knowledge and the further development of expertise in the field of engineering. IJMEAS is since the beginning independent from any non-scientific third-party funding. The establishment of the journal was supported between 2023 with grants from the Yayasan Ghalih Pelopor Pendidikan (Ghalih Foundation). All members of IJMEAS work on an honorary basis. The journal is hosted by Ghalih Publishing, the publishing house of the Ghalih Academic and University Library.

Abstract

Dissimilar aluminum alloys welding between AA5xxx and AA6xxx presents significant challenges due toifferences in chemical composition, thermal properties, and electrochemical potential, all of which impact the corrosion resistance of the welded joints. AA5xxx alloys are well-known for their excellent corrosion resistance, particularly in marine environments, while AA6xxx alloys exhibit superior mechanical strength. This study provides a comprehensive investigation into the influence of various welding techniques—such as Gas Metal Arc Welding , Gas Tungsten Arc Welding , Laser Arc Welding, Laser Beam Welding, and Friction Stir Welding on the corrosion behavior of dissimilar joints between AA5xxx and AA6xxx. Each welding process induces distinct microstructural changes within the Fusion Zone and Heat-Affected Zone, which subsequently affect the joint's susceptibility to various corrosion mechanisms, including galvanic corrosion, intergranular corrosion, pitting corrosion, intermetallic corrosion, and stress corrosion cracking (SCC). Additionally, the difference in thermal expansion coefficients between AA5xxx and AA6xxx can generate residual stresses at the joint, exacerbating the risk of corrosion. This paper also explores mitigation strategies, including the optimization of welding parameters, the application of post-weld heat treatment, and the use of anticorrosive films through protective coatings to enhance corrosion resistance and extend the service life of the welded structures. The findings from this research offer comprehensive insights into the corrosion mechanisms in dissimilar alloys welding between AA5xxx-AA6xxx joints, providing practical guidance for optimizing welding processes. This paper aims to support the long-term performance of AA6xxx and AA5xxx aluminum alloy structures, particularly in critical industrial applications and environments demanding high corrosion resistance.

Abstract

The inspection and testing of the vertical pressure vessel at PT. X were conducted to assess its structural integrity and ensure operational safety. The study focused on thickness and hardness measurements, along with computational stress analysis using the Finite Element Method (FEM). The results revealed an average material thickness of 4.98 mm and an average hardness of 130 HV, indicating compliance with basic material specifications. Stress distribution analysis showed maximum hoop stress of 221.429 MPa and longitudinal stress of 88.111 MPa, both within the material's allowable stress limit of 285.18 MPa. Static displacement analysis identified a maximum displacement of 6.553 mm and a minimum of 0.018 mm, with clear visualization of deformation patterns. These findings confirm the vessel's design safety and its ability to withstand operational pressures without failure.
