摘要： The present invention provides a method for the welded joining of dissimilar metal materials in a butt welding configuration. The technique described in the present invention allows dissimilar metal materials to be welded by means of the action of a laser beam without requiring the prior machining of the parts to be welded or to prepare the V-shaped joint. The method is applicable in the automotive, naval, or aeronautic industry.
