Abstract

A process for welding a component in which a recess is filled by welding tracks is provided. The process includes providing a recess with a contour which delimits an outer upper surface of the component with respect to the recess. The welding tracks are laid such that the welding tracks also reach the surface outside a contour of the recess and that a plurality of welding layers are used in order to fill the recess until a last layer protrudes completely beyond the surface.
