In this work, pulsed laser cleaning was conducted on 5083 aluminum alloy plates for removing the oxide film and improving the surface quality. The chroma was innovatively introduced to evaluate the surface quality of cleaned samples. Samples with good cleaning quality were successfully achieved by means of process optimization involving single factor and orthogonal laser cleaning tests. The optimum cleaning parameters for desirable effect consisted mainly of average power of 40 W, scanning speed of 2500 mm/s and repetitive frequency of 85 kHz. On this basis, a well-formed welded joint can be obtained because of the removal of the oxide film on the surface of aluminum alloy. It has been found that the maximum stress and strain of joints subjected to laser cleaning were up to 102.5 % and 114.81 % of joints laser welded in the absence of laser cleaning, respectively. Significant improvement in mechanical strength was mainly attributable to effective suppression of porosities in welds on account of the removal of oxides with the assist of pulsed laser cleaning.
