- 文章介绍了窄间隙热丝TIG焊的研究现状及其系统的构成,并对其技术、经济特性进行了分析。窄间隙热丝TIG焊是一种比较具有竞争优势的焊接工艺方法,焊接过程无飞溅,焊接稳定性高,不存在清渣问题,比较容易解决窄间隙侧壁熔合关键问题。焊接接头具有更小的变形、更低的残余应力,抗裂性好,并具有优异的接头机械性能和焊缝质量,在板较厚、焊接质量要求较高的场合已得到越来越广泛的应用。
The composition of the narrow gap hot wire TIG welding system(hot wire NG-TIG) and the developing situation at home and abroad are introduced.And the technical and economical characteristics of the hot wire NG-TIG are analyzed.Compared with other narrow gap welding processes,the hot wire NG-TIG has competitive advantages such as no splash during welding course,high welding stability and no welding slag cleaning problem.In addition,it is easier to solve the key problem of narrow gap side wall fusion.The welds are of low distortions,low residual stresses,good cracking resistance,superior mechanical properties and excellent weld seam quality.And the hot wire NG-TIG gets more and more attentions and applications in the cases of thicker wall and higher welding quality demand.2011,2(2): 42-44,5,6 收稿日期：2010-4-21分类号：TE973.3作者简介：张良锋(1982-),男,湖南隆回人,工程师,2007年毕业于哈尔滨工业大学材料加工工程专业,硕士,主要从事焊接工艺研究与开发.参考文献：
