Abstract

This study aims to investigate the effects of welding on the fatigue and crack behavior of ASTM A36 steel, a low-carbon steel commonly used in various applications, particularly in pressure vessel transport tanks for preventing environmental and health problems due to liquid petroleum gas (LPG) transport tank leaks. This research evaluates the influence of welding on the material’s properties through various testing methodologies, including impact and fatigue tests. The impact tests were conducted using the Charpy V-Notch method, while fatigue tests employed the repeated bending method. The specimens were subjected to testing at different temperatures and angles to evaluate their performance under various conditions. The findings indicate that welding introduces weaknesses in the material, affecting its impact energy and fatigue life. Visual observations and metallographic examinations further revealed the fracture characteristics and microstructural changes in welded and non-welded specimens.
