Abstract
Independent of the geometrical complexity of a laser metal deposition component, the fundamental geometrical element is given by basic weld seams most of the times. These weld seams are deposited on a surface area and therefore not suitable to generate lattice structures. In this study, it is successfully demonstrated that basic spot welds can be used to achieve a vertical columnar built-up of pillars. Tilting of these pillars was used to merge them or to form forks. In that way, laser metal deposition of a lattice structure was implemented. © 2018 The Authors. Published by Elsevier Ltd. This is an open access article under the CC BY-NC-ND license.
