A　solid-state　and　continuous　groove　repair　technology　was　proposed　for　aluminium　alloy　based　on　friction　rolling　additive　manufacturing　(FRAM).　The　feasibility　of　FRAM　was　explored　by　repairing　three　types　of　prefabricated　groove　damages　in　aluminium　alloy　plates.　A　well-repaired　joint　for　trapezoidal　groove　was　obtained　when　the　press-in　depth　of　the　tool　head　was　2　mm.　The　press-in　depth　was　the　key　factor　to　complete　filling　of　the　groove　damage.　Effective　grain　refinement　of　the　repair　centre　and　the　significant　refinement　area　are　observed,　which　leads　to　the　hardness　of　these　two　areas　reaching　99%　and　102%　of　the　substrate,　respectively.　The　material　migration　behaviour　of　the　filling　material　during　the　process　was　clarified.
