Dissimilar Aluminum Alloys

Dissimilar aluminum alloys, AA2024-0 and AA7075-T6 were laser welded on both sides in a T-joint configuration using a low power fiber laser. The effect of welding speed (9, 12, 15, 18 and 21 mm/s) on weldability was evaluated at laser power of 270W with argon gas as the shielding gas. The sample welding angle was fixed at 45° with an interval of 180 seconds between each welding pass. Macrograph observations revealed that full penetration with pore free weld of these dissimilar joint was obtained at the laser parameters of 270 W and 9 mm/s, suggesting that lower welding speed is preferred during low power laser welding.
