Abstract Honeycomb-structure is an important sealing structure of the aeroengine, and the demand is increased with
the development of aeronautics and astronautics. The automation of tailor welded honeycomb is one of effective way to
realize the high efficiency production of honeycomb. In this paper, the position accuracy of welding spot which is the key
problem during automatic process of honeycomb and the disadvantage of original process and control system are analyzed.
Two kinds of position control mode under ACR9000 are proposed to make welding spot accuracy: one is based on the motor
encoder; The other is based on multi-axis synchronization. The results showed that two methods can achieve the requirement
of position accuracy of welding spot, and can ensure high quality and high efficiency production of honeycomb.
