Title Forming characteristics and dimensional control of thin-walled components with plasma arc and wire addictive manufacture

Abstract Additive Manufacturing (AM) technology is an advanced surfacing manufacturing technology, paper, wire arc increasing material manufacturing technology base, to study the low-carbon steel thin-walled structures of plasma arc surfacing molding and dimensional characteristics its surfacing during the process parameters。源-于,优Y尔O论U文.网wwW.youeRw.com 原文+QQ75201,8766

First experimental low-carbon steel wire rod based plasma arc single-channel single-layer surfacing, research reactors cladding member formed dimensions (layer width, the height) and process parameters (current surfacing, surfacing speed, filler wire speed) between relations, to determine the appropriate process parameters for surfacing straight wall member, repeatedly adjusting the process parameters to the stack deposited straight wall member in more than 80 layers of different composition and properties of the straight wall member analysis in contrast, choosing the right upright wall member, study the relationship between straight walls forming size and process parameters surfacing between the member。 How to get fast and efficient multi-layer thin-walled straight wall surfacing member concluded。
