摘　　要：介绍了自行研制的25 t惯性摩擦焊机的组成、功能和主要技术指标,该焊机具备轴向和径向功能,焊接线速度可达20 m/s,在该焊机上焊接的高温镍基合金K418与高强钢42CrMo的惯性摩擦焊接头强度>756 MPa,合格率>95%,铜与钢径向焊接接头抗剪强度>200 MPa。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 he gained by this machine.
