Abstract:
The paper presents the experimental investigation of the laser welding of high-strength aluminum-lithium alloys of Al-Cu-Li and Al-Mg-Li system followed by the thermal processing, aimed to the production of a high-strength weld joint. It is founded that the thermal processing (quenching, artificial ageing) of the welded joint increases its strength, however the variation of the microstructure and phase composition is different for the two systems of the alloys. The thermal processing permits getting the tensile strength of the welded sample of 0.9 of the basic alloy strength for Al-Cu-Li and 0.95 for Al-Mg-Li.
