| Abstract Scope |
Aluminum alloys are widely utilized in the advanced manufacturing of structural components due to their high strength-to-weight ratio and excellent corrosion resistance. Fabrication of aluminum structures often involves fusion processes such as laser welding, which can present challenges, including susceptibility to welding cracks and deformation. This study experimentally investigates the effect of key laser welding parameters on thin aluminum alloys panels. To this end, three different types of aluminum alloy samples (3003-H14, 5052-H14, and 6061-T6) were welded using varying laser power and scanning speeds. Microscopic images are taken to qualitatively analyze the differences between the various laser parameters on the aluminum panels. To determine the possible severity of strength degradation before material property testing, Raman spectroscopy was used to evaluate oxidation levels of the laser welded samples. The results provide insight into how laser welding parameters affect the overall integrity of the joints. |
