Application of Additive Manufacturing for the Repair of Forging Dies

Abstract

In this paper the investigated conditions and possibilities of repairing forging dies with high precision robotic MAG welding are presented. Different welding wire electrodes were examined and compared by their processability. Productivity, process stability, slag and fume formation were in the focus of investigation. Metallographic tests were carried out to validate the compliance of welded layers. Based on the performance of the wire electrodes, recommendations have been elaborated for the procedure specification and also for further investigation. Some robot cell layouts have been designed adapting to the special working environment and requirements of the welding procedure.
