The Influence of Wire Properties on the Quality and Performance of Wire+Arc Additive Manufactured Aluminium Parts

Wire+arc additive manufacture (WAAM) is a high build rate process for production of near-net shape components layer by layer. The performance and quality of the deposited metal are heavily affected by the properties of wires, which are the raw materials for WAAM. Therefore there may be higher requirements for the qualities and properties of wires for WAAM than for welding. External surface qualities, micro hardness, composition and...
