Alloy　2060-T8　is　a　newly　developed　high-strength　Al-Li　alloy　for　applications　in　aircraft　industry.　Crack-free　welds　were　obtained　in　laser　beam　welding　with　5087　filler　wire　under　optimized　welding　conditions.　In　this　paper,　fusion　zone　microstructure　and　joint　mechanical　properties　were　investigated.　Microstructure　typical　for　the　weld　metal　consists　of　alpha-Al　matrix　with　a　few　nanoscale　precipitates　inside　and　a　coarse　icosahedral　quasi-crystalline　T-2　phase　at　the　dendritic　and　grain　boundaries.　The　quasicrystalline　occurred　normally　in　Al-Li-Cu　alloys　with　higher　Li　contents.　Our　investigations　show　that　the　icosahedral　quasicrystalline　phase　T-2　phase　forms　in　the　laser-welded　Al-Li　alloy　2060　with　lower　Li　content　as　a　result　of　segregation　and　replacement　of　Mg　element.　The　joint　tensile　strength　in　as-welded　condition　is　around　317　MPa,　about　63%　of　that　of　the　base　metal,　and　fracture　occurs　within　the　fusion　zone.　(C)　2015　Elsevier　Ltd.　All　rights　reserved.
