三种窄间隙焊接技术的特性比较与应用选择
Characteristic comparison and application selection of three narrow gap welding technologies
摘要
Abstract
Narrow gap welding has higher productivity,better performance and lower cost.For some misunderstandings in practical applications of narrow gap welding,the advantages and limits of three different commonly used welding technologies are analyzed such as NG-SAW,NG-Hot wire pulsed TIG welding and NG-MAG welding.For practical applications,NG-MAG welding is proposed for higher productivity,higher quality of welded joints and lower cost.NG-Hot wire pulsed TIG welding could be used when weld's mechanical performance is prior than productivity and cost,and NG-SAW could be adopted for downhand welding when stability of welding process and welding quality are prior.关键词
