摘要
Abstract
In this article, it introduced slag system selection of flux used for X100 pipeline steel submerged-arc welding, alkalinity range determination, as well as analysis on welding process and mechanical performance Using H03MnNi3MoTiB wire which is matched with X100 to conduct double wire submerged-arc welding test, the results indicated that the quality of weld and HAZ both meet the requirements of API SPEC 5L , but some black spot exist in bead surface. The composition of black spot is iron oxide by energy spectrum analysis, a kind of improved approach of removing black spot, increasing slag protection and reducing the content of oxygen in weld, is proposed, so the prescription for excellent flux to X100 pipeline steel has been obtained.关键词
