In　this　study,　AA1060　aluminum　alloy　and　T2　copper　with　a　thickness　of　3　mm　were　joined　by　Yb:YAG　Disc　laser　welding.　Three　joint　types,　namely　laser　fusion　welding　(LF　joints),　laser　deep　penetration　braze-fusion　welding　(LPBF　joints)　and　laser　deep　penetration　braze　welding　(LPB　joints)　were　obtained　depending　on　the　amount　of　melted　copper　in　the　Al/Cu　interface.　Furthermore,　the　micro-hardness　and　mechanical　properties　of　these　joints　were　investigated　in　detail.　The　experimental　results　show　that　the　tensile　strengths　of　LF　joint,　LPB-F　joint　and　LPB　joint　are　79　MPa,　94.5　MPa　and　52　MPa,　respectively.　A　maximum　tensile　strength　is　obtained　in　LPB-F　joint,　which　is　close　to　that　of　the　1060　aluminium　alloy.　The　primary　reason　is　that　Al2Cu3　and　Al2Cu　intermetallic　compounds　with　a　comparatively　greater　hardness　exist　in　the　transition　layer.
