摘要
Aluminum-lithium alloys are ideal high-strength lightweight structural materials, which have extensive applications in aerospace, weapon and other hi-tech industrial areas. By using a Slab CO2 laser, 1420 aluminum-lithium alloy has been welded. The mechanical properties of the welded joint have been studied after adding different wires and postweld heat treatment process.
