ABSTRACT
Wire arc additive manufacturing technique is a new promising approach based on the melting of feedstock wire using an electric arc. It is gaining more popularity than its contemporary additive manufacturing processes for metal additive manufacturing due to its capability of economically producing large-sized components with relatively high deposition rates. Wire arc additive manufacturing (WAAM) technique has the ability to produce near-net-shape application-based components with reasonably acceptable surface roughness. End-use components need to be machined using appropriate machining methods. Several process selection parameters and computer-aided process planning need to be addressed to establish the capability of WAAM to produce near-perfect components of particular materials. Primary process selection criteria include computer-aided design model parameters, tool path generation, welding process, welding process parameters, shielding gas, and wire selection. This chapter introduces the process planning criterion in WAAM, starting with an overview of process planning parameters and their selection strategies.
