2024 Aluminium was welded by domestic manufactured continuous type friction welder. The problems and optimum condition were studied in 2024 Al-2024 Al cases. Mechanical tests and microstructure analysis were studeid. Interfacial temperature of welding was predicted by FDM. The obtained results are as follows: 1) In case of Al-Al, the optimum condition range was wide. 2) At the boundary zone, fine recrystallized zone was not harmful to the mechanical property and no growth of precipitation was observed. 3) In case of Al-Al, temperature gradient can be predictedby FDM and heat input can be taken as weld parameter.
