Impact Analysis of Welding Sequence to Reduce Weld Deformation in Aluminum Hulls
Journal of Marine Science and EngineeringAluminum hulls, which are preferred in the marine industry due to their durability, corrosion resistance, and lightweight properties, face serious challenges due to thermal deformation during welding. This study aims to predict and minimize transverse deformations due to welding sequences for a transverse model in the lower part of an aluminum hull. To
