Abstract: The present disclosure relates to an eccentric extreme high-speed-rate laser hybrid manufacturing method for a rotary engineering component. By positioning an extreme high-speed-rate laser direct energy deposition machining head at a predetermined eccentric distance, the damage caused by reflected light to the machining head is effectively reduced, to prolong a service life of the machining head. Also a conventional form of a molten pool in extreme high-speed-rate laser direct energy deposition can be changed, namely from a “falling” form caused by a high-speed movement and a gravity to a “climbing” form. Thus, in extreme high-speed-rate laser direct energy deposition machining, the molten pool has a longer time to fully contact a surface of the rotary engineering component to form desirable bonding performance.
