“…Peng et al [27] conducted an assessment of a SLM process as well and included a summary of different conducted LCAs on additive manufacturing technologies. In addition to comprehensive LCA studies, assessments are often only based on process energy efficiency analyses, e.g., by Catalano et al [28] for a laser metal-wire deposition (LMWD) process. Although stand-alone LCA studies often induce comparability by, e.g., assessing the same impact categories or even using similar system boundaries, they are not meant to be used for direct comparison.…”

Process planning in manufacturing today focuses on optimizing the conflicting targets of cost, quality, and time. Due to increasing social awareness and subsequent governmental regulation, environmental impact becomes a fourth major aspect. Eventually, sustainability in manufacturing ensures future competitiveness. In this paper, a framework for the planning of sustainable manufacturing is proposed. It is based on the abstraction and generalization of manufacturing resources and part descriptions, which are matched and ranked using a multi-criteria decision analysis method. Manufacturing resources provide values for cost, quality, time and environmental impacts, which multiply with their usage within a manufacturing task for a specific part. The framework is validated with a detailed modeling of a laser machine as a resource revealing benefits and optimization potential of the underlying data model. Finally, the framework is applied to a use case of a flange part with two different manufacturing strategies, i.e., laser metal-wire deposition and conventional milling. The most influential parameters regarding the environmental impacts are the raw material input, the manufacturing energy consumption and the machine production itself. In general, the framework enabled the identification of non-predetermined manufacturing possibilities and the comprehensive comparison of production resources.

“…Several techniques exist for the delivery of material to the substrate surface, depending on the material's form as shown in Figure 1. Wire-fed systems typically result in high quality claddings with minimal surface roughness [8], high deposition rates [9], and lower costs or environmental impact compared to other manufacturing processes [10,11]. This study proposes the modification of laser welding equipment for laser cladding of corrosion-resistant Inconel 52M wire [12] on low carbon, low alloy steel which has high strength and good formability but poor corrosion resistance [13].…”

Laser-assisted wire cladding has emerged as a popular method for the surface modification and repair of components as it provides cleaner processing environments, reduced costs with higher material deposition rates, and better surface finish. However, the high capital cost of laser cladding systems can be detrimental to their adoption in industry. This work presents a favourable option for industry by using a traditional 6 kW Ytterbium-doped fibre laser welder retrofitted with a MIG welder wire-feeding system to obtain laser cladded surfaces without specialized laser cladding equipment. A high dynamic range camera is used to observe material deposition modes, which influence the coating and surface quality. Process-related mechanisms are proposed to explain the observed deposition modes, along with an analysis of the process parameters that influence the clad characteristics. By carefully selecting the process parameters in this non-traditional laser cladding option, defect-free depositions with good surface finish can be achieved.
