摘要： A method for joining busbars includes reshaping a raw laser beam to obtain a reshaped laser beam. The reshaped laser beam comprises a core focus portion and at least one ring focus portion. The core focus portion and the ring focus portion are coaxial with respect to one another. The ring focus portion surrounds the core focus portion. The method further includes directing the reshaped laser beam to a plurality of busbars to weld the plurality of busbars to one another along at least one weld seam.
