Dissimilar　joining　of　CFRP　and　conventional　metal　attracts　tremendous　interest　due　to　the　increased　usage　of　CFRP　in　the　aerospace　industry.　However,　until　now,　laser　joining　of　CFRP　to　metal　is　commonly　performed　with　low　welding　velocity　(＜20　mm/s),　which　limits　its　practical　applications　due　to　the　low　joining　efficiency.　In　this　work,　both　experiments　and　simulations　were　conducted.　The　defect-free　CFRP/AA2060　laser　joint　was　achieved　with　a　laser　power　of　5　kW　and　a　welding　velocity　of　110　mm/s.　Compared　with　the　Gaussian　laser　beam,　a　rectangular　beam　spot　was　obtained　using　an　integrated　mirror　in　the　present　study.　The　rectangular　beam　spot　provided　a　relatively　uniform　energy　density,　thus　offering　a　uniform　temperature　distribution　at　the　CFRP/　AA2060　interface,　minimizing　the　porosity　defect　as　well　as　exhibiting　the　high　shear　force.　More　importantly,　the　CFRP/AA2060　joints　were　achieved　over　a　wide　range　of　joining　parameters,　indicating　superior　adaptability　of　the　laser　joining　CFRP　to　metals　with　the　rectangular　beam　spot.
