摘要

双钨极TIG电弧具有低电弧压力特性，能够在大电流下避免驼峰、咬边等缺陷，提高熔敷效率。为将其应用于增材制造，采用单丝输送和双丝输送两种模式，针对200 A以上的大电流双钨极TIG电弧，研究熔敷电流、送丝速度、行走速度对熔敷成形的影响。结果表明，在单丝输送模式下， 200~350 A电流范围内，送丝速度过快会导致熔敷道铺展不良，而在350 A以上，送丝速度过快会导致插丝缺陷；采用双丝输送模式，能提高电弧熔丝热效率，有效降低插丝倾向，提高熔敷效率。最终得出200~650 A电流下的最大许用送丝速度和行走速度范围，为双钨极TIG电弧增材制造提供了成形良好的工艺窗口。双钨极TIG电弧增材在650 A熔敷电流下依然能够成形良好，熔敷效率达到5.36 kg/h。

Abstract

The double-tungsten TIG arc has low arc pressure characteristics, which can effectively avoid humping and undercutting at high currents and improve the deposition rate. To apply it to additive manufacturing, single wire feeding mode and dual wire feeding mode were used in this paper. For the high-current double-tungsten TIG arc above 200 A, the effects of deposition current, wire feed speed and travel speed on the forming characteristics of the deposition bead are studied. The results show that for the single wire feeding mode, within the range of 200~350 A deposition current, too high wire feeding speed will lead to poor spreading of the deposition bead, while above 350 A, too high wire feed speed will lead to wire insertion defect. For the dual wire feeding mode, the thermal efficiency of the arc melting wire can be improved, effectively reducing the tendency of wire insertion and improving the deposition rate. The maximum permissible wire feed speed for each deposition current from 200 A to 650 A and the travel speed range were finally derived, providing a well-formed process window for double-tungsten TIG arc-based additive manufacturing. The double-tungsten TIG arc-based additive manufacturing can be formed well at 650 A, with a deposition rate of 5.36 kg/h.
