Abstract
A laser weld seam with reduced end crater and a process for production thereof are provided. The seam end is provided at a location, which exhibits a excessive material relative to the surrounding surface or thereby, that the seam towards the seam end exhibits a counter-running direction change of its preferred direction, which is designed in such a manner, that as a consequence of the interaction between cooling forward and counter-running seam a backfill of the melt towards the seam end occurs.
