AB Aluminium alloys exhibit eco-friendly aspects related to global environmental issues, such as almost unlimited recyclability.Nevertheless, some intrinsic characteristics are challenges to explore all their benefits. In the welding process, the highthermal conductivity and low melt point require high control of heat input. Alternatively, the pulsed laser mode provides asharp beam focus with precise control enabling regulating the energy delivered. In this sense, this present work analysed theeffect of pulsed laser welding parameters on 3-mm-thick AA5083 aluminium alloy sheets. Trials targeted to develop soundwelds with minimum defect and high penetration depth adopting statistical methods. The optimum parameter arrangementwas achieved by varying peak power, spot diameter, and pulse duration. Finally, the best parameter combination was appliedusing different pulse shapes to mitigate crack formation and pores. As a result, the pulse shape with step-down at the end ofeach pulse generated crack-free spot welds.
