A method for welding at least two aluminum-containing components is provided. The components have an aluminum content of at least 75% by weight. The method includes subdividing an output laser beam into multiple partial beams directed onto the components, so that multiple laser spots are generated on a surface of the components, and traversing a welding contour on the surface of the components with the multiple laser spots. Laser spot centers of at least three laser spots of the multiple laser spots are arranged in a ring formation. The output laser beam is generated by a multifiber, so that each laser spot of the multiple laser spots on the surface of the components has a core portion and a ring portion, with a mean power density in the core portion being higher than a mean power density in the ring portion.
