Acta Metallurgica Slovaca, 2022 The paper provides a novel technique for merging graphene nanoplatelets (GNPs) within aluminium matrix (AA 6061) by continuous drive friction welding (CDFW). The welding processes were done at 1400 rpm and 2000 rpm rotational speeds with two different frictional loads 2000 N and 2500 N for 5 sec and 7 sec welding times. The welded joints were subjected
