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.
