Abstract: A method for laser beam joining of at least two joining partners, in which a laser beam device produces a continuous weld seam along an application path with a preferably very long path length. Irregularities in the weld seam due to high process speeds are avoided as follows: in a first process step, at least two weld seam sections spaced apart from one another in the longitudinal direction of the path, are respectively produced with an intermediate weld seam interruption. In a second process step the laser beam device produces in each weld seam interruption a further weld seam section, such that all weld seam sections merge together without interruptions, in particular with formation of the continuous weld seam.
