High-strength　aluminum　alloy　have　become　one　of　the　most　commonly　used　metal　materials　for　aerospace　and　automotive　application　parts　due　to　its　high　strength，low　density，excellent　ductility　and　corrosion　resistance.　Wire　arc　additive　manufacturing（WAAM）has　the　ability　to　rapidly　in-situ　form　and　manufacture　complex　structural　parts，and　is　very　suitable　for　the　manufacturing　of　medium　or　large　high-strength　aluminium　alloy　parts.　The　current　status　of　high-strength　aluminum　alloy　WAAM　processes　and　equipment，the　inherent　properties　and　defects　of　high-strength　aluminum　alloy　WAAM，and　the　main　performance　optimization　methods　were　comprehensively　analyzed　in　this　paper.　The　inherent　characteristics　of　the　microstructure　and　properties　as　well　as　the　impact　of　hybrid　additive　manufacturing　technologies　on　the　microstructure　and　properties　were　discussed.　Opinions　are　put　forward　on　issues　such　as　metallurgical　defects，characteristic　performance　requirements，the　advantages　and　disadvantages　of　various　optimization　processes　in　WAAM.　Development　directions　such　as　a　comprehensive　evaluation　system，　composition　design　and　wire　development，　special　heat　treatment　systems　and　synergy　of　composite　additive　manufacturing　technology　are　proposed.　Such　proposals　are　expected　to　provide　references　for　the　performance　improvement　and　application　promotion　of　high-strength　aluminum　alloys　manufactured　via　WAAM.　©　2024　Beijing　Institute　of　Aeronautical　Materials　(BIAM).　All　rights　reserved.
