Abstract

A welding method and system for battery poles, wherein the method is applied to a control device in a welding system. The welding system further comprises a movable welding device (402), and a welding module (4021) and a ranging sensor (4022) which are arranged on the movable welding device (402). The method comprises: acquiring a set of pole coordinates, in a welding station coordinate system, of a plurality of poles of a battery; on the basis of the set of pole coordinates and welding quantity information of a welding module (4021), determining a set of welding coordinates of the welding module (4021); acquiring welding heights corresponding to welding coordinates in the set of welding coordinates, wherein the welding heights are determined on the basis of height distances between a ranging sensor (4022) and poles corresponding to the welding coordinates, which height distances are collected by means of the ranging sensor (4022); and on the basis of the set of welding coordinates and the welding heights corresponding to the welding coordinates, controlling the welding module (4021) to weld the poles of the battery. By means of the welding system, welding quality problems caused by non-uniform heights of poles are reduced, thereby improving the yield of batteries.
