AGV operation method and system for welding

The invention relates to an AGV operation method and system for welding, and relates to the field of the AGV technology, and the method comprises the steps: obtaining a station identification image; determining an in-place signal based on the station identification image; when the in-place signal is received, workpiece integration information on the corresponding station is identified based on the station identification image; a welding track of the corresponding station is formed based on the workpiece integration information; according to the AGV trolley welding method and device, the driving wheels on the AGV trolley and the lifting mechanism are controlled to operate in a matched mode on the basis of the welding track, and the effects that welding of the current station can be conducted by placing the identification code with the welding mode of the current station on the corresponding station, editing of a whole set of process is not needed, and the welding fluency and the working efficiency of the AGV t
