The effect of heat treatment on the properties of CO2 laser welded Al-2.45%Li-0.02%Cu-0.11%Zr (in wt. %) alloys is presented. This examination was an attempt to archive strength levels comparable to unwelded base alloy. Thermal treatment consisting of solutionizing at 550 degrees centigrade for 2 h and ageing at 175 degrees centigrade for 4 and 8th after welding was necessary to archive adequate labels of the 0.2% proof stress, the yield strength and elongation.
