厚板常用弧焊工艺的技术和经济特性比较
Comparison of technical and economic characteristics of common arc welding process for heavy plate
摘要
Abstract
SMAW,SAW,NG-SAW,GMAW and NG-GMAW are applied often in structures with thick plates.In this article,we investigated and compared the filling area in groove,heat input,welding parameters,mechanical properties of weld,residual strain and production cost for those welding technologies.Finally,we came to a conclusion that NG-GMAW involves higher productivity,higher strength of welding joint,lower residual strain and over 40％～80％ substantial reduction in cost.关键词
