Abstract
Description
technical field
[0001] The present application relates to the technical field of laser welding, and more specifically, relates to a pressure cylinder structure and laser welding equipment. Background technique
[0002] The function of the Busbar (bus bar, bus bar) of the power battery module is mainly to realize the electrical connection between the battery cells. At present, the laser welding of the Busbar of the power battery module generally has unsatisfactory welding surface effects, such as excessive weld reinforcement, severe welding spatter, etc. In order to obtain a good welding effect, the use of a ring spot laser can also make The welding effect has been improved, but the cost of the ring spot laser is much higher than that of the traditional spot laser. Therefore, it is necessary to develop a pressure cylinder structure that attaches the Busbar to the pole of the power battery module and protects the position of the welding seam through shielding gas.
