In addition to standard additive technologies, such as Selective Laser Melting (SLM), other additive technologies are increasingly being used, including Directed Energy Deposition (DED). DED offers several advantages and is utilized both for producing entire components and for repairing damaged parts through weld cladding. In this study, the possibility of weld cladding of nickel-based hard alloys using DED was tested using a laser as the energy source to melt the additive material. The tests performed showed that selected nickel alloys, suitable for mould repair, are difficult to weld. Therefore, the experiments sought optimal process parameters and defined the accompanying technological operations in order to produce a crack-free weld cladding.
