Decarburization of Wire-Arc Additively Manufactured ER70S-6 Steel

Materials, 2023
Decarburization is an unwanted carbon-loss phenomenon on the surfaces of a material when they are exposed to oxidizing environments at elevated temperatures. Decarburization of steels after heat treatment has been widely studied and reported. However, up to now, there has not been any systematic study on the decarburization of additively manufactured ...

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 ...
