摘要

某公司制作的常减压装置材质为304L(D)双牌号不锈钢,为研究其焊接性能,分别对304L(D)双牌号不锈钢、普通的304L不锈钢和304不锈钢进行了埋弧焊试验,对焊接接头进行了宏观检测、无损检测及组织性能等对比分析,得到了304L(D)钢埋弧自动焊工艺参数,并验证了其焊接性能优势,为304L(D)双牌号不锈钢的实际生产提供参考。

Abstract

In order to study the welding performance of 304L（D） dual-brand stainless steel made by a company,submerged-arc welding tests were carried out on 304L（D）dual-brand stainless steel, 304L stainless steel and 304 stainless steel respectively, and the macro-examination, non-destructive inspection and comparative analysis on the structure and properties of the welded joint were carried out.The technological parameters of SAW of 304L（D） double grade stainless steel were obtained and the performance advantages of 304L（D） double grade stainless steel were verified, which can provide reference for the actual production of 304L（D） double-brand stainless steel.
