Method for the laser welding of a workpiece with a rapid change between welding zones having different materials to be welded

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

• directing a laser beam onto the workpiece by using scanner optics, and
• in an arbitrary order with the laser beam, welding a first component to a base part of the workpiece at least in a first welding zone, and welding a second component to the base part in a second welding zone,
• wherein the first component and the second component comprise different materials at least in the first welding zone and the second welding zone,
• wherein
• a laser energy of the laser beam is capable of being split variably at least between a core fraction, corresponding to a core beam of the laser beam, and a ring fraction, corresponding to a ring beam of the laser beam that encloses the core beam,
• and wherein the splitting of the laser energy between the core fraction and the ring fraction is selected differently for welding in the first welding zone and for welding in the second welding zone.
