(a–c) Effects of AW-LSF parameters on the hardness profiles of the weld beads for FZ, PFZ, HAZ, and BM. (a) Welding current. (b) Welding speed. (c) Laser shock frequency. (d) Hardness distribution profile of the weld seam of the AW (welding current is 130 A, and welding speed is 140 mm/min) and the AW-LSF (welding current is 130 A, welding speed is 140 mm/min, and laser shock frequency is 10 Hz).
