Journal of Materials Processing TechnologyRésumé
In this work, a 5754 Al alloy and T40 were joined in butt configuration by focusing a fiber laser onto the titanium side, close to the weld centerline (offset). The keyhole was made entirely of titanium, and the fusion of the aluminum was achieved by heat conduction. Neither filler metal nor chamfering was necessary to produce a sound, dissimilar weld. The assembly was free from porosity and spatter defects. The mechanical properties were satisfactory. The energy input, the laser offset, and their interaction had statistically significant effects on the ultimate tensile strength. The findings of this investigation prove the robustness and suitability of fiber laser offset welding for Al–Ti weld fabrication.
