抄録

AZ61 magnesium alloy plate with 0.6mm thickness was friction seam welding using a rotating disk. The rotating disk was made with SUS304 stainless steel to 100mm in diameter, 10mm in thickness. The microstructure of the weld interface showed finer than that of the base metal. The weld interface had an irregularity. The hardness of weld zone of the joint showed lower value than the base metal. The maximum tensile shear load of the joint was 2.4kN under conditions of down welding and welding speed 4mm/s.
