Arc Behavior in Wire Arc Additive Manufacturing Process

Procedia Manufacturing, 2020
Abstract The welding arc behavior in a wire arc additive manufacturing process was studied while building a ten-layer wall over a base plate using a cold metal transfer (CMT) power source. The real-time recorded welding current, voltage, thermal cycles at the base plate, and the synchronized high-speed arc images with each deposited layer were used ...

An Extensive Review On Wire Arc Additive Manufacturing

International Journal For Multidisciplinary Research, 2023
Wire arc additive manufacturing (WAAM) is a production process used to 3D print or repair metal parts. It belongs to the Direct Energy Disposition (DED) family of Additive Manufacturing process. WAAM is executed by depositing layers of metal on top of each other, untill a desired 3D shape is generated.
