英文摘要: |
The constitution and characteristics of the self-developed 25 t inertia friction welding machine are introduced in this paper. This machine can implement inertia axis friction welding and inertia radial friction welding with 20 m/s maximal linear velocity. The strength of a welded joint of nickel-alloy K418 and high-strength steel 42CrMo is more than 756 MPa, and the qualified rate is more than 95%. The shear-strength more than 200 MPa of copper-steel can also be gained by this machine. |
