The Influence of Heat Input on the Surface Quality of Wire and Arc Additive Manufacturing

Wire and arc additive manufacturing has unique process characteristics, which make it have great potential in many fields, but the large amount of heat input brought by this feature limits its practical application. The influence of heat input on the performance of parts has been extensively studied...
