Abstract A friction welding method for linking different metals features that one or more grooves are made on the end face of harder metal, a simple plane is made on the end face of softer metal, two metals do relative rotation at high speed on friction welder while a sufficient axial force is applied to them, and the plastic deformation on the end face of softer metal takes place to squeeze the end face into the grooves on the end face of harder metal for firm linking between them. Its advantages are low cost and high link strength.
