Method for splash-free welding, in particular using a solid-state laser

A method for laser beam welding a workpiece, the method comprising:

• generating at least a first beam area on the workpiece by a first laser beam;
• and
• generating a second beam area on the workpiece by a second laser beam,
• wherein the first beam area and the second beam area are guided in a feed direction relative to the workpiece,
• wherein centroids of the first beam area and the second beam area are not coinciding,
• wherein the first beam area runs ahead of the second beam area,
• wherein a length (LE1) of the first beam area, measured transversely to the feed direction, is greater than or equal to a length (LE2) of the second beam area,
• a surface area of the first beam area is greater than a surface area of the second beam area,
• wherein a width (BE1) of the first beam area, measured in the feed direction, is greater than or equal to a width (BE2) of the second beam area,
• wherein a laser power of the first laser beam is greater than a laser power of the second laser beam, and
• wherein the second laser beam is irradiated into a weld pool generated by the first laser beam.
