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 ...
