Abstract

The development of technology in the maritime sector is very rapid in the manufacture of aluminum ships. Friction Stir Welding (FSW) is a green technology in the metal joining process. Post Welding Heat Treatment (PWHT) is one way to increase the loss of strength of the material connection after the FSW process. The purpose of this study was to determine the effect of FSW results before and after PWHT. Aluminum alloy (AA) series 5052 and 6061 were used as research materials because they are resistant to seawater. FSW parameters were spindle speed 1500 rpm (clockwise), travel speed 30 mm/min, tool depth 0.2 mm, and tool tilt 1o. PWHT parameters were heating the FSW material in a furnace to a temperature of 550°C (10, 30 minutes), water quenching, and artificial aging to a temperature of 180°C for 7 hours. The material was characterized by tensile testing, hardness, and micrography. The highest tensile strength and hardness values were 216 MPa and 68 HV, the smallest and uniform grain size in the weld zone and base metal areas were obtained at PWHT parameters of 30 minutes.

Abstract

The Bulk Transfer System on Supply Vessels plays a crucial role in supporting offshore logistics, particularly in transferring bulk cement to drilling facilities. The system operates on pneumatic principles and is influenced by compressors, piping networks, mechanical components, and control devices. However, the current maintenance approach remains reactive, increasing the risk of recurring operational failures. This study aims to evaluate system reliability and determine an optimal risk-based maintenance strategy using Reliability Centered Maintenance (RCM). The analysis includes system function identification, Failure Mode and Effect Analysis (FMEA), and Logic Tree Analysis (LTA). The results show that the transfer pipeline has the highest risk (RPN 48), followed by the air compressor unit, air receiver tank, and safety system (RPN 36). LTA indicates that most failures are evident with Operational Consequences, while safety system failures are categorized as Safety Consequences. The application of RCM effectively improves overall system reliability.

Abstract

Friction Stir Welding (FSW) is a welding method that does not use filler materials. FSW has been widely used in the maritime industry. The purpose of this study is to analyze the effect of FSW joints before and after Post Weld Heat Treatment (PWHT) on 5052 and 6061 aluminum alloy materials. The FSW parameters include a spindle speed of 1500 rpm (clockwise), a travel speed of 30 mm/min, a tool depth of 0.2 mm, and a tool tilt angle of 1°. The PWHT parameters involve heating the FSW material to 550°C, with holding times of 45 and 90 minutes, followed by water quenching. The subsequent process is artificial aging up to a temperature of 200°C for 6 hours. The materials were then subjected to tensile testing, hardness testing, and micrographic examination. The results showed that the highest values were achieved using FSW parameters with 90 minutes of PWHT, yielding the maximum tensile strength and hardness values of 264 MPa (27.5%) and 89.6 HV (37.4%). Furthermore, the smallest and most uniform grain size was quantitatively observed at 4.9 µm in both the weld zone and the base metal.
