Abstract

The invention relates to a method for joining at least two components (1, 2) by means of laser beam welding, wherein the at least two components (1, 2) are arranged at least partially in an overlap joint. According to the invention, it is provided that the at least two components (1, 2) are joined by means of - one in an internal welding area (B i ) of a total welding area (B) internal laser weld seam (L) i ) with a predefined weld contour and - one in an external welding area (B a ) of the total welding area (B) introduced, the inner welding area (B i ) at least partially surrounding outer laser weld seam (L a ) are joined together with a predetermined weld contour, whereby - the inner laser weld seam (L i ) with predefined welding parameters and the outer laser weld seam (L a) with further specified welding parameters that differ from the specified welding parameters in a respective welding area (B i , B a ) of the two components (1, 2) arranged in the overlap joint.
