This not only reduces the time of production, but also helps to improve the quality of the parts produced [8–11]. Laser Cladding – Additive Manufacturing | SpringerLinkA typical laser cladding machine for additive manufacturing consists of a laser source, a processing head, a numeric control, and an enclosure. Material can be added in the form of a wire or a powder feed. The necessary laser power depends on the material and the targeted deposition rate.
