The brief review is presented about weldability of aluminium alloys using a laser radiation. The effect of different factors on the stability of penetration of alloys and formation of joints, being free of any most widely spread defects, such as pores, cracks, oxide inclusions, is shown. The lack of necessary information about the load-carrying capacity of aluminium alloy joints made by the laser welding under the complex conditions of loading is outlined.
Keywords: laser welding, aluminium alloys, penetration depth, reflectivity, energy density, plasma flame, shielding gases, weld pool, pores, cracks
