Welding method and welding system for post terminal

The invention provides a welding method and a welding system for a pole column, relates to the technical field of battery production, and aims to at least solve the quality problems of insufficient welding, welding deviation and the like in the welding process in the prior art. The welding system comprises a control device, a manufacturing execution system and welding equipment, and the control device is used for sending a target welding coordinate of each pole to the welding equipment under the condition that a first target verification result represents that verification is successful and a pressing result of a pressing plate mechanism in the welding equipment represents that pressing is completed. The downward pressing result of the pressing plate mechanism is determined based on the height feature information of the pressing plate mechanism and the height feature information of the confluence assemblies corresponding to the multiple pole columns, and the target welding coordinates of the pole columns are
