In this paper, an automatic WAAM technology is proposed to realize the gradient additive remanufacturing of ultra-large hot forging dies. Firstly, a vertical manufacturing strategy and normal are meet different demands. Secondly, basic principle layering design dies developed, wear resistance Ni-based, Co-based, Fe-based alloys at room temperature high analyzed. The Co-based alloy has best high...

This article provides an overview of the latest developments in field hybrid additive manufacturing metal parts. The concept and various kinds are discussed. Special attention is paid to hybridization technologies processes forming: die forging, deep drawing, others. background significance technologies, as well their applicability production presented. combination with forming carried out a du...
