    <title language="eng">Influence of build-up height on residual stresses in additive repair and modification of multi-material composites using DED-Arc</title>
    <abstract language="eng">The application of steels with a higher yield strength allows reductions in wall thickness, component weight and production costs. Hybrid additive manufacturing based on Gas Metal Arc Welding (GMAW) processes (DED-Arc) can be used to realise highly effi-cient component modifications and repairs on semi-finished products and additively manufactured structures. There are still a number of key issues preventing widespread implementation, particularly for SMEs. In addition to the manufacturing design, detailed information about assembly strategy and geometric adaptation of the component for modifications or repairs are missing. These include the welding-related stresses associ-ated with the microstructural influences caused by the additive manufacturing steps, particularly in the transition area of the substrate and filler material interface. The present research focuses the effect of component height on residual stress distribution. Defined specimens were welded fully automatically with a high-strength solid wire (yield strength &gt; 790 MPa) especially adapted for DED-Arc on S690QL substrate.</abstract>
