摘要

针对基于钨-惰性气体的线弧快速成型制造（WAAM-TIG）方法，引入并研究了一种新颖的多线进给机制，以最大限度地减少线进给方向的依赖性。通过采用三个独立的送丝器，开发出了安装在氩弧焊枪周围、相距 120° 的三线并行送丝机构，前后侧送丝的综合效果最大程度地降低了送丝方向对沉积珠的依赖性。该机制与单丝送丝进行了比较，发现几何均匀性、材料沉积率和总体比能量要求分别提高了 26%、66% 和 56%，且电弧稳定性良好。

Development of concurrent multi wire feed mechanism for WAAM-TIG to enhance process efficiency

A novel multi wire feed mechanism has been introduced and investigated for tungsten-inert-gas-based wire arc additive manufacturing (WAAM-TIG) method to minimise the dependency of wire feed direction. The concurrent three wire feed mechanism mounted 120° apart around the TIG torch was developed by employing three independent wire feeders, and an integrated effect of front-back-side feeding minimised the dependency of the wire feeding direction on the deposited bead. The mechanism was compared with the single wire feed, and geometrical uniformity, material deposition rate and overall specific energy requirements were found to improve by ∼26%, ∼66% and ∼56%, respectively, with good arc-stability.
