PENGARUH PUTARAN DAN KECEPATAN TOOL TERHADAP SIFAT MEKANIK PADA PENGELASAN FRICTION STIR WELDING ALUMINIUM 5052
Abstract: Aluminium is a metal
that has a good resistance against corrosion, this is because the occurrence of
the phenomenon of pasivasi. In addition to its resistance to corrosion,
aluminium also has a lighter weight compared to steel, so aluminium is frequently
used as one of the materials used in the manufacture of ships, especially on
the upper deck of the building, insulation, fuel tanks and freshwater tank.Welding is the process of
connecting between two or more metal parts by using thermal energy.In general
aluminum welding using fusion welding processes such as Metal Inert Gas and
Metal Inert Gas, but on both of these methods there is possibility formation of
defects are porosity, cracks and prone to occurringdeformationduringcooling
processof dan the formation ofmetalwelding. The purpose of this study was to
determine the effect of tool rotation and welding speed on the mechanical
aspect of Aluminium 5052 with the friction stir welding method.The parameters
of the welding process is done on the
research this is is the round tool and welding spee is is the round tool and
welding speed.
Round tool used there are two namely 1800 rpm and 1100 rpm. The speed of
welding is also used there are two variations,namely 11.4 mm/min and 19.8
mm/min. As for the mechanical tests conducted there are three, namely testing
the hardness, impact test, and tensile testing.The result of this research was
the discovery that the round tool and welding speed greatly affect the
mechanical properties of aluminium that has been welded. Because the tool is
rotating faster increases the tensile strength of aluminium, while the small
welding speed will increase the hardness of aluminum that has been welded.
