Abstract：

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.
