| Abstract Scope |
The manufacturing of aluminum structures often involves welding aluminum alloys to create lightweight, mechanically robust components. However, the chemical and mechanical differences among various types of aluminum alloys pose significant challenges to achieving high-quality welds. These challenges are particularly critical in the production of advanced aluminum structures, such as electric vehicle (EV) battery enclosures, which demand precise and efficient welding techniques, including laser welding. This study presents a simulation model developed in COMSOL Multiphysics to replicate the laser welding of aluminum alloys. The model incorporates phase transformation effects to accurately capture the interactions between laser parameters and the resulting weld microstructure, while also accessing weld quality. It evaluates key welding parameters, such as energy input, beam focus, and scanning speed, to analyze their impact on weld quality, providing insights for achieving optimal welding conditions. |
